Organs (What makes up Organs)

Tissues

Tissue

When you think of human identity, what comes to mind

At the beginning of the week we discussed systems and organ structures that are common to all humans.

Over the year we will be looking at processes that occur in all of our bodies.

But what makes us special?

Tissue Basics

Tissues –are groups of cells that are similar in structure that work together to perform a specific function. There are four main tissue types:

Epithelium Connective tissue Muscle Nervous tissue

Epithelium

Epithelium or epithelial tissue, forms the linings, coverings, and

glandular tissue of the body. ▪ One type of epithelium forms the outer layer

of the skin▪ Another type of epithelium lines the air sacs

of the lungs Cells in epithelium are packed tightly

together to form continuous sheets

Connective Tissue Connective tissue protects, supports, and

binds together other body tissues. Connective tissue is made up of different

types of cells in varying amounts of a nonliving substance around the cells, called the matrix.

Examples of connective tissue include: Bone Cartilage Adipose tissue (fat) Blood??? Really, how

Muscle Tissue Muscle tissue is specialized to

contract and cause movement. There are three main types of

muscle tissue: Skeletal muscle Cardiac muscle Smooth muscle

Give Examples of the location and function of each muscle type?

Nervous Tissue Nervous tissue is composed of specialized

cells called neurons that receive and send electrical signals in the body.

Nervous tissue responds to stimuli and transmits impulses and together with supporting cells, makes up the brain, spinal cord, and nerves.

Essential Questions

1. What are the main types of tissue in the human body?

2. How does the structure of a type of human tissue relate to its function in the body?

Practice Loading a Gel…

Practice filling each well Wear Gloves throughout Don’t contaminate with

your DNA Don’t poke holes in gel Don’t create air bubbles Keep the plunger

depressed until after you have raised the micropipettor away from the gel

67

Practice Loading GelsMost common loading problems

taking up too much sample with the micropipettor,

taking up air in addition to the sample,

not completely expelling the sample,

sucking the sample out of the well once placed,

poking the pipette tip through the bottom of the gel well.

68

Practice Loading a Gel… Set fake gel into casting trey Secure casting trey into chamber well- line

Part 1 DNA Digestion w Restriction Enzymes - Day 1 of Lab

1. Obtain 4 micro-centrifuge tubes 2. Label tubes 1-4 with some way to ID

them later.Very Important: Note the content of

each tube in your lab journal. You will need to know what is in each tube. Don’t get them mixed up!!!

3 Dispense DNA and Enzymes into 4 tubes as instructed in activity.

4. Incubate in 37 T water bath X 45 to 60 min.

5. Begin Student Resource Sheet.

70

Essential Question

1. What is the structure and function of DNA

2. How does DNA differ from person to person

3. What role does DNA play in our Identity

71

How to Use a Micropipettor

Place a new tip on the micropipettor, being careful to not touch the tip to any surface.

Depress the plunger to the first stop and hold it in this position.

Dip the tip of the micropipettor into the top of the solution to be transferred.

Gradually release the plunger and draw the fluid into the tip, making sure to keep the tip in the solution.

Slide the pipet tip out along the inside wall of the reagent tube to dislodge any excess droplets adhering to the outside of the tip.

Check to make sure there are no air bubbles in the sample in the tip. If there are air bubbles, expel the sample using the directions below and restart procedure.

72

How to Use a Micropipettor

Insert the tip of the micropipettor into the area in which you want to expel the liquid.

Slowly depress the plunger to the first stop to expel the sample and continue to depress the plunger to the second stop to ensure all of the liquid is expelled.

Hold the plunger in the depressed position. Slide the micropipettor out with the plunger

depressed. Do not release the plunger from the depressed position to avoid sucking any liquid back into the tip.

Once the tip is out of the liquid, release the plunger. Eject the tip into the proper disposal area by pressing

down on the tip-ejector button

Polymerase chain reaction (PCR) What is it?

A Biochemical technique used to amplify the number of copies of a specific region of DNA generating thousands to millions of copies of a particular DNA sequence in order to be adequately tested.

Named after the enzyme, polymerase, which copies DNA in cells.

It’s a chain reaction because multiple events occur in succession, over and over again in the

same sequential order.

Each time the series of events is completed, one cycle has been completed.

74

Polymerase chain reaction (PCR)

Some of the uses of PCR: Cloning Diagnosis of hereditary diseases Paternity testing Diagnosis of infectious diseases Forensic sciences

Restriction Enzymes are derived from bacteria with the ability to cut DNA from invading organisms such as a viruses, before the virus takes control of the cell

Restriction

Enzymes

Gel Electrophoresis

1. DNA is obtained from the skeletal remain

2. Gene is amplified by PCR

3. DNA is cut in specific places by the use of restriction enzymes.

4. The restriction enzyme recognizes specific nucleotide sequences and cuts DNA

Restriction enzymes are derived from Bacteria

Gel Electrophoresis What is it?

The process where DNA can is separated according to size and electrical charge by applying an electric current to them.

The current forces the molecules through pores in a thin layer of gel.

DNA is negatively charged so it runs toward the positive pole

78

Why DNA electrophoresis

To visualize the DNA fragments and sort them according to size

DNA samples are loaded into a gel and exposed to electrical currents Fragments run through

the gel at different rates smaller = faster

Ready to Go

1. Place gel in tray, and tray in chamber.

2. Be sure the wells are at the negative end of the gel and the tray is secure in the notch

3. Fill with TAE Buffer, cover gel completely

4. Fill the wells with the corresponding sample

5. Copy table in notes!!!!

84

Special Notes

Be sure the voltage is set at 150 and the timer is set for 15 minutes

Check polarity! Be sure the DNA sample is at top of the negative pole (black) and will run down toward the positive

Alarm will sound after 15 minutes…check back every 2-5 min if incomplete

Turn off the power supply when the dye is near the bottom edge of the gel

Be careful to not allow the dye to run off the edge of the gel

85

Polarity

If the polarity is backwards, the DNA will migrate out of the well and off the short end of the gel. If the mistake is caught in time, the polarity can be reversed and the DNA will migrate back into the well and then through the longer portion of the gel.

86

Staining

The DNA fragments are then stained with a dye and can be observed as lines or bands in the gel when view on a light box.

87

Gel Staining

Often the DNA fragment bands can be observed directly after electrophoresis without further treatment. If the bands are faint or appear to be missing, the gel can be soaked in the diluted Carolina Blue dye for 30 minutes and then washed with distilled water

88

Results of DNA electrophoresis

89

Don’t Go Past Here

90

Results of DNA electrophoresis You will actually find that the gel

results show that both of the missing persons match the DNA fingerprint of the DNA from bone digested with Enzyme 1

NOTE that Lane D and F are the same ad B. (see the example gel picture below).

If you only cut with 1 enzyme you may come up with incorrect data.

91

Results

You will have to look to the results for Enzyme 2 to make their final conclusions regarding identity.

Gel results show that when using a second restriction enzyme on the same DNA, only one Restriction Fragment Length matches that from the bone sample.
