Using DNA Fingerprinting for Determining Familial Relationships

In a war torn country, two youngboys were separated from theirrespective parents who had beenimprisoned by the regime. Thechildren were cousins who wereborn two months apart and lookedstrikingly similar. Their mothers werehalf sisters who shared a commonmother. After several years, theregime was overthrown andreplaced by a new governmentthat released all political prisonersfrom prison. The prisoners werereinstated in their respectivecommunities and all chargesagainst them were dropped.

During this period, the two boys had not been separated from eachother, and had been adopted by a high ranking military officer whohad no children of his own. Both the officer and his wife died in aliberation uprising and for a short period of time the boys wereplaced in an orphanage. On their 18th birthday, the boys werereleased from the orphanage and they immediately began tosearch for information regarding their lost parents.

The brothers contacted a number of elders from their village. Theelders informed them that after their biological parents were re-leased from prison, one of the fathers was assassinated by individualswho were sympathetic to the fallen regime. The second biologicalfather was suffering from amnesia. Two women, who were thought tobe their biological mothers, were in a rehabilitation facility whichhoused approximately 200 women.

Upon arrival to the center it was very obvious that the patients hadnot received proper medical attention. Based on age and appear-ance, about 10 women fit the profile of the two mothers.

Since the boys were cousins and their mothers were sisters whoshared the same mother (who was the grandmother of the boys),the first identification screening test performed was a mitochondrialDNA fingerprinting. Mitochondrial information is inherited onlythrough the female (mother). It was expected that the mitochon-drial testing results would be identical for the two boys. Mitochon-

Using DNA Fingerprinting for Determining Familial Relationships

drial DNA fingerprinting tests are also less expensive than chromo-somal DNA testing and results are available in a shorter period of time.Results showed that two women did have the same matching mito-chondrial DNA fingerprinting pattern which also matched that of thetwo boys.

In order to match the boys with the correct mothers and the survivingfather, chromosomal DNA fingerprinting tests were ordered for theboys, the mothers and the surviving father. The DNA fingerprint of oneof the boys matched with the surviving father and one of the mothers.The DNA fingerprint of a child is a composite of elements (matchingvisible DNA bands on the gel) from both parents. The pattern is easilyrecognizable and can be experimentally demonstrated in this simula-tion experiment.

Chromosomal deoxyribonucleic acid (DNA), present in the nucleus ofevery living cell, is the genetic material that acts as a blueprint for allof the proteins synthesized by that cell. In mammals, however, a largefraction of the total DNA does not encode protein and serves noobvious function. Polymorphic DNA refers to chromosomal regionsthat vary widely from individual to individual. By examining several ofthese regions within the genomic DNA obtained from an individual,one may determine a “DNA Fingerprint” for that individual. DNApolymorphisms are now widely used for determining paternity/maternity, kinship.

Mitochondrial DNA is inherited from the mother. A human eggcontains a large number of mitochondria. Unlike that, human spermcontains a small number of mitochondria. Upon fertilization of thehuman egg by a sperm, the zygote contains the majority of mito-chondria obtained by maternal genetic inheritance. Unlike mito-chondrial DNA, nuclear cell DNA is an equal composite of bothparents. In each chromosome pair, one is inherited from the fatherand the second from the mother.

PREPARING THE GEL BED

1. Close off the open ends of a cleanand dry gel bed (casting tray) byusing rubber dams or tape.

A. Using Rubber dams:

• Place a rubber dam on eachend of the bed. Make surethe rubber dam fits firmly incontact with the sides and bottom of the bed.

B. Taping with labeling or masking tape:

• With 3/4 inch wide tape, extend the tape over the sidesand bottom edge of the bed.

• Fold the extended edges of the tape back onto the sidesand bottom. Press contact points firmly to form a goodseal.

2. Place a well-former template (comb)in the first set of notches at the end ofthe bed. Make sure the comb sitsfirmly and evenly across the bed.

CASTING AGAROSE GELS

3. Use a 250 ml flask to prepare the gel solution. Add the followingcomponents to the flask as specified for your experiment (refer toTable A).

• Buffer concentrate• Distilled water• Agarose powder

Activity One - Agarose Gel Preparation and Practice Gel Loading

At high altitudes, it isrecommended to use amicrowave oven toreach boilingtemperatures.

4. Swirl the mixture to disperse clumps of agarose powder.

5. With a marking pen, indicate the level of the solution volume onthe outside of the flask.

6. Heat the mixture to dissolve the agarose powder. The finalsolution should appear clear (like water) without any undissolvedparticles.

A. Microwave method:

• Cover the flask with plastic wrap to minimize evapora-tion.

• Heat the mixture on High for 1 minute.• Swirl the mixture and heat on High in bursts of 25 seconds

until all the agarose is completely dissolved.

B. Hot plate method:

• Cover the flask with aluminum foil to prevent excessevaporation.

• Heat the mixture to boiling over a burner with occasionalswirling. Boil until all the agarose is completely dissolved.

Check the solution carefully. If you see "crystal" particles, the agaroseis not completely dissolved.

Activity One - Agarose Gel Preparation and Practice Gel Loading

7. Cool the agarose solution to 55°Cwith careful swirling to promoteeven dissipation of heat. Ifdetectable evaporation hasoccurred, add distilled water tobring the solution up to theoriginal volume as marked on theflask in step 5.

After the gel is cooled to 55°C:

If you are using rubber dams, go to step 9.If you are using tape, continue with step 8.

8. Seal the interface of the gel bed and tape to prevent the agar-ose solution from leaking.

• Use a transfer pipet to deposit a small amount of cooledagarose to both inside ends of the bed.

• Wait approximately 1 minute for the agarose to solidify.

9. Pour the cooled agarose solution into the bed. Make sure thebed is on a level surface.

10. Allow the gel to completely solidify. It will become firm and coolto the touch after approximately 20 minutes.

PREPARING THE GEL FOR ELECTROPHORESIS

11. After the gel is completely solidified, carefully and slowly removethe rubber dams or tape from the gel bed.

Be especially careful not to damage or tear the gel wells when removingthe rubber dams. A thin plastic knife, spatula or pipet tip can be insertedbetween the gel and the dams to break possible surface tension.

12. Remove the comb by slowly pulling straight up. Do this carefullyand evenly to prevent tearing the sample wells.

13. Place the gel (on its bed) into the electrophoresis chamber,properly oriented, centered and level on the platform.

14. Fill the electrophoresis apparatus chamber with the requiredvolume of diluted buffer for the specific unit you are using (seeguidelines in Table B).

For DNA analysis, the same EDVOTEK 50x Electrophoresis Buffer is usedfor preparing both the agarose gel buffer and the chamber buffer. Theformula for diluting EDVOTEK (50x) concentrated buffer is 1 volume ofbuffer concentrate to every 49 volumes of distilled or deionized water.

Activity One - Agarose Gel Preparation and Practice Gel Loading

The electrophoresis(chamber) bufferrecommended is Tris-acetate-EDTA (20 mMtris, 6 mM sodiumacetate, 1 mM disodiumethylenediaminetetraacetic acid) pH 7.8.Prepare the buffer asrequired for yourelectrophoresisapparatus.

Activity One - Agarose Gel Preparation and Practice Gel Loading

If you are using transferpipets, gently squeeze thepipet stem, instead of thebulb to help control thedeliveryof smallsamplevolumes.

PRACTICE GEL LOADING

Accurate sample delivery technique ensures the best possible gelresults. Pipeting mistakes can cause the sample to become dilutedwith buffer, or cause damage to the wells with the pipet tip whileloading the gel.

If you are unfamiliar with loading samples in agarose gels, it is recom-mended that you practice sample delivery techniques beforeconducting the actual experiment. EDVOTEK® electrophoresisexperiments contain a tube of practice gel loading solution for thispurpose. Casting of a separate practice gel is highly recommended.One suggested activity is outlined below:

1. Cast a gel with the maximum number of wells possible.

2. After the gel solidifies, place it under buffer in an electrophoresisapparatus chamber.

Alternatively, your teacher may have cut the gel in sectionsbetween the rows of wells. Place a gel section with wells into asmall, shallow tray and submerge it under buffer or water.

Note: The agarose gel is sometimes called a "submarine gel" because it issubmerged under buffer for sample loading and electrophoretic separation.

3. Practice delivering the practice gel loading solution to thesample wells. Take care not to damage or puncture the wellswith the pipet tip.

• For electrophoresis of dyes, load the sample well with 35-38microliters of sample.

• If using transfer pipets for sample delivery, load each samplewell until it is full.

4. If you need more practice, remove the practice gel loadingsolution by squirting buffer into the wells with a transfer pipet.

5. Replace the practice gel with a fresh gel for the actual experi-ment.

Note: If practice gel loading is performed in the electrophoresis chamber,the practice gel loading solution will become diluted in the buffer in theapparatus. A small amount of practice gel loading solution (filling up to 12wells) will not interfere with the experiment, so it is not necessary to preparefresh buffer.

LOADING THE SAMPLES

1. Check the Sample Volumes

Sometimes a small amount of sample will cling to the walls ofthe tubes. Make sure the entire volume of sample is at thebottom of the tubes before starting to load the gel.

• If your samples are in Quickstrip™ connectedtubes, tap the foil top of the strip so samplesfall to the bottom of the tubes.

• If your samples are in individual 1.5 ml or 0.5 mlmicrotest tubes, briefly centrifuge the sampletubes, or tap each tube on the tabletop toget all the sample to the bottom of the tube.

2. Load Samples

Load each of the dye samples in tubes A - F intothe wells in consecutive order. The amount ofsample that should be loaded is 35-38 µl.

Electrophoresis of Dyes

Staining is not required for Experiment # S-49, butresults must be analyzed upon completion of theelectrophoretic separation. Because dye moleculesare extremely small they will diffuse out of the gel.Thus, the gel cannot be saved.

7. After approximately 10 minutes,you will begin to see separationof the colored dyes.

8. After the electrophoresis iscompleted, turn off the power,unplug the power source,disconnect the leads andremove the cover.

9. Document the gel results.

A variety of documentationmethods can be used, includ-ing drawing a picture of the gel,taking a photograph, orscanning an image of the gelon a flatbed scanner.

Suggestions for Lesson Plan Content

This teacher-generated lesson plan outline can be used as a guide-line for classroom discussion. Connections to the National Contentand Skills Standards follow the plan.

1. Have students write a creative scenario that is based on theanalysis of the gel, or divide students into small groups and haveeach group write a short play based on the evidence obtainedfrom the gel. Share scenarios with the class or give class time fora “short” play performance.

2. Using electrophoresis to separate DNA fragments as used in areasother than establishing biological relationships. Have studentsconduct an “On-line” search to see how this procedure is use inthe following cases:

• Identifying individuals that are carriers of genetic disease• Identifying men and women killed in service• Forensics

3. Discuss the importance of being meticulous in the collection andanalysis of DNA that will be used as evidence in court cases.

4. From the vocabulary list below, have students write applicationsentences about each:

DNA mitochondria nucleusElectrophoresis DNA Fingerprinting polymorphic DNA

Use pictures or drawings from textbooks and other resources tohelp explain the vocabulary words to the students.

DNA Fingerprinting is a method that allows for the matching andidentification of the source of unknown DNA samples. It canprovide positive identification with great accuracy. DNA finger-printing involves the electrophoretic analysis of DNA fragmentsizes obtained from a person’s DNA.

5. List and discuss with students the essential parts of an experiment.

• Writing a logical hypothesis• Making careful observations• Differentiating between an experiment and an control• Identifying variables• Predicting experimental outcomes• Recording results in a concise and accurate manner• Drawing valid interpretations of results• Formulating alternative explanations

BATCH AGAROSE GEL PREPARATION

To save time, the agarose gel solution can be prepared in a batch forsharing by the class. Any unused prepared agarose can be savedand remelted for gel casting at a later time. For a batch (375 ml)preparation of 0.8% agarose gel:

1. Use a 500 ml flask to prepare the diluted gel buffer.

• Add 7.5 ml of buffer concentrate

• Add 367.5 ml of distilled water.

2. Pour 3.0 grams of UltraSpec-Agarose™ into the prepared buffer.Swirl to disperse clumps.

3. With a marking pen, indicate the level of solution volume on theoutside of the flask.

4. Heat the agarose solution as previously described for individualgel preparation. The heating time will require adjustment due tothe larger total volume of gel buffer solution.

5. Cool the agarose solution to 55°C with swirling topromote even dissipation of heat. If evapora-tion has occurred, add distilled water to bringthe solution up to the original volume (375 ml) asmarked on the flask in step 3.

Pre-Lab Preparations

6. Dispense the required volume ofcooled agarose solution forcasting the gels. The volumerequired is dependent upon thesize of the gel bed (refer to TableA for individual gel castingguidelines).

7. Allow the gel to completelysolidify. It will become firm andcool to the touch after approxi-mately 20 minutes. Then proceedwith preparing the gel for electro-phoresis.

55˚C

Note: The UltraSpec-Agarose™ kit component isoften labeled with the amountit contains. In many cases, theentire contents of the bottle is3.0 grams. Please read the labelcarefully. If the amount ofagarose is not specified or ifthe bottle's plastic seal hasbeen broken, weigh the agaroseto ensure you are using thecorrect amount.

ELECTROPHORESIS SAMPLES IN PRE-ALIQUOTEDQUICKSTRIP™ CONNECTED TUBES

The electrophoresis samples in this experiment are packaged in pre-aliquoted Quickstrip™ connected tubes.

1. Use sharp scissors to separate each set oftubes A-H in the block of samples.

Each row of samples (strip) constitutes acomplete set of samples for each gel. Thenumber of samples per set will varydepending on the experiment. Some tubesmay be empty.

2. Cut carefully through the foil between therows of samples. Do not cut or puncturethe foil covering the top of the sampletubes.

3. Each group will require one strip ofsamples.

4. Remind students to tap the foil or tubesbefore gel loading to ensure that all ofthe sample is at the bottom of the tube.

Notes regarding electrophoresis

1. Do not move the apparatus immediately after the samples havebeen loaded.• Moving the apparatus will dislodge the samples from the wells

into the buffer and will compromise results.• If it is necessary to move the apparatus during electrophore-

sis, you may safely do so after the tracking dye has migratedat least 1 cm from the wells into the gel.

2. For optimal separation, do not use voltages higher than 125 voltsfor agarose gel electrophoresis. Higher voltages can overheatand melt the gel.

3. Electrophoresis should be terminated when the dyes have moved3 to 4 centimeters from the wells and before it moves off the gel.

AVOIDING COMMON PITFALLS

Potential pitfalls and/or problems can be avoided by following thesuggestions and reminders listed below.

• To ensure that dyes are well resolved, make sure the gel formula-tion is correct (see Table A) and that electrophoresis is conductedfor the optimal recommended amount of time.

• Correctly dilute the concentrated buffer for preparation of boththe gel and electrophoresis (chamber) buffer. Remember thatwithout buffer in the gel, there will be no sample mobility. Useonly distilled water to prepare buffers. Do not use tap water.

• For optimal results, use fresh electrophoresis buffer preparedaccording to instructions.

• Before performing the actual experiment, practice sampledelivery techniques to avoid diluting the sample with bufferduring gel loading.

• To avoid loss of samples into the buffer, make sure the gel isproperly oriented in the electrophoresis unit so the samples arenot electrophoresed in the wrong direction off the gel.

Study Questions and Answers

1. What do the different dye bands that were separated by electro-phoresis represent?

The different dyes represent DNAs with variable lengths obtainedfrom the DNAs of the mother, child and fathers.

2. Why do different individuals, such as siblings, have individual(different) fingerprints?

Chromosomes which are matched pairs are derived one from thefather and the second from the mother. The two copies of agene at a specific focus of the chromosome represents theunique genotype for the particular offspring.

3. What is the basis of mitochondrial DNA fingerprint analysis?

Mitochondrial DNA is inherited from the mother. A human eggcontains a large number of mitochondria. Unlike that, humansperm contains a small number of mitochondria. Upon fertilizationof the human egg by a sperm, the zygote contains the majority ofmitochondria obtained by maternal genetic inheritance.

4. What is the difference between mitochondrial and cell DNA-based fingerprinting analysis.

Unlike mitochondrial DNA, nuclear cell DNA is an equal compos-ite of both parents. In each chromosome pair, one is inheritedfrom the father and the second from the mother.
