All characteristics or traits of organisms are encoded or contained in the master plan or
RNA Proteins
DNA Carbohydrates
DNA
Describe the basic structure of thisDNA molecule as Watson & Crick would.
Double helix
DNA consists of repeating subunits called?
Nitrogen bases Amino acids Nucleotides
Name the three parts of a
DNA nucleotide?
Name the two nitrogen bases that make up
purines?
Name the two nitrogen bases that make up pyrimidines?
When two strands of DNA are
together Adenine always binds with________.
Adenine with Thymine
The entire molecule below is
known as…
Who are the two scientists that were monumental in discovering the structure
of DNA?
W_____ & C_______
If an elm tree, an elk and an eel have the same genetic code, why do they all look
different?
The sequence or order of the nitrogen bases.
How can organisms be so different from each other if their genetic material is made of the same four nucleotides?
The differences result from the sequence or order of the 4 nitrogen bases.
During DNA replication the complimentary DNA sequence
for ATT GAC is ?
When two strands of DNA are together
Guanine always binds with _______?
The backbone of a DNA molecule is made of which two components?
P______ & D______
Phosphate and deoxyribose(sugar)
Where is DNA located in a cell?
CytoplasmRough ERNucleus
Nuclear membrane
Nucleus
What is the process that forms mRNA?
TranslocationTranscription
Translation
The order of _____ bases in DNA allows each one of us to be
unique?
How is RNA different than
DNA?(tell me two ways)
RNA… •one strand •contains ribose •thymine is replaced by uracil
Where does translation occur?
Nucleus CytoplasmNucleolus
What are the three structures that are
needed for translation?
Hint: 3 different RNAs
What structure contains the
anti-codon & an amino acid?
tRNA mRNA rRNA
tRNA
What does a codon finally
code for?
ProteinCarbohydrate
Lipid
Many amino acids strung together by
peptide bonds form a ______________
Carbohydrate Lipid
Protein
Phosphate
Protein
In the cell, where does mRNA start & end up?
Starts in Nucleus
Ends in the cytoplasm
I f mRNA has a AUG UGC code what is the anti-
codon that is located on tRNA?
AUG UGC UAC ACG
What is the function of tRNA?
What 2 things does it bring for translation?
Brings anti-codon
& amino acid
What is the first step in transcription?
mRNA nucleotides attach to DNA
DNA unwinds & unzipsmRNA is formedDNA replicates
DNA unwinds & unzips
Adenine is to thymine as guanine is to ____.
A change in the DNA sequence that also
changes the protein it codes for is called a ____?
GeneticsMutation Mutagen
Heredity
A mistake of one nitrogen base, it is called a
____mutation. An example is sickle cell anemia.

The best general statement for transcription? mRNA nucleotides attach to DNA DNA unwinds & unzipsmRNA is formedDNA replicates
mRNA is formed
Why does transcription occur---
Why can’t DNA deliver the message?
DNA can’t leave the nucleus,its too big!!!
The grouping of three nitrogen basesis known as…
If mRNA is GCU,the anti-codon on tRNA is…
Making proteins never stops.Name a place in our body where proteins end up.
The process of converting a mRNA code into an amino acid.
Transcription TranslationTranlocation Mitosis
X-rays, ultraviolet lights& radioactive substancescan change the DNA code.They are all known as ____
Mutations MutagensTranslators Enzyme errors
What part is missing in this nucleotide?
What is the process that is occurring below?
Transcription TranslationTranlocation Replication
Transcription

What is the amino acid if mRNA is AGU?
What is the amino acid ifmRNA is AAA?
What is the amino acid ifmRNA is GUA?
What is the amino acid ifmRNA is AUG?
What is the amino acid ifmRNA is GGA?
