DNA 100
The four chemicals that make up the
human genome are called:
a. Phosphates
b. Nitrogen bases
c. Nucleotides
d. Deoxyribose sugars
DNA 200
The process by which DNA copies itself is
know as:
a. transcription
b. translation
c. replication
d. mutation
DNA 300
DNA copies itself with the help of
which of the following:
a) mRNA
b) RNA polymerase
c) DNA polymerase
d) ribosomes
DNA 400
Describe the structure of DNA by doing the
following:
1. List the three parts of a nucleotide
2. Describe the base pairing rules (how do the
bases match up with each other)
3. Describe the role and location of hydrogen
bonds in a DNA molecule
1. Phosphate, deoxyribose (sugar),
nitrogenous bases (A,T,G,C)
2. A pairs with T, G pairs with C
3. Hydrogen bonds are located between each
pair of bases; they hold the two strands of
DNA together
DNA 500
a. A sample of DNA contains 12% adenine by
weight. What are the percentages of the
other three bases?
b. Will the DNA strand in part a be more or less
stable than a DNA strand with 24% adenine
by weight? Explain
a. 12% thymine, 38% guanine, 38% cytosine
b. More stable - G and C base pairs have three
hydrogen bonds whereas A and T base pairs have 2
hydrogen bonds
Transcription 100
The purpose of transcription is to:
a) Produce gametes
b) Duplicate DNA
c) Make mRNA from the DNA
d) Correct mutations in DNA
Transcription 200
The purpose of RNA polymerase is
a) To copy DNA
b) To bring amino acids to the ribosome
c) To read DNA and make an RNA copy
d) To split apart the DNA double helix
Transcription 300
The purpose of mRNA is to:
a) Bring instructions on how to make a
protein to the ribosomes
b) Help the DNA double helix to copy
itself
c) Bring amino acids to the ribosomes
d) Make up the structure of the
ribosomes
Transcription 400
A segment of DNA reads TACCGCGTTATG.
How many amino acids does this code
represent and what is the RNA sequence
that would be transcribed from this?
4 codons which represents 4 amino acids.
AUG GCG CAA UAC
Transcription 500
Translation 100
The purpose of translation is to
a) Create a protein from instructions on
mRNA
b) To make mRNA from DNA
c) To produce amino acids
d) To copy the DNA
Translation 200
In order for mRNA to do its job, it must get
to which location in the cell?
a) The nucleus
b) The mitochondria
c) The cell membrane
d) The ribosomes in the cytoplasm
Translation 300
Which of the following statements about translation
is correct?
a) The ribosome reads the instructions on the
tRNA to make a protein
b) The mRNA is used to make more copies of DNA
for when the cell divides
c) tRNA molecules bring the correct amino acid to
the ribosome
d) mRNA is created from the DNA
Translation 400
The are circled in red
in the picture is a:
a) Codon
b) Anticodon
c) Amino acid
d) Nucleotide
QuickTime™ and a
TIFF (Uncompressed) decompressor
are needed to see this picture.

Misc 100
A change in the genetic code is called a:
mutation
Misc 200
Which of the following is true of genes?
a) They are made of chromosomes
b) They are the instructions to make
proteins
c) They found inside the ribosomes
d) They are used to make amino acids
Misc 300
Which of the following mutations in the DNA code
TACGGATCT would result in the greatest change in
the protein that would result?
a. Changing the first T to a C
b. Inserting a G between the first two bases
c. Changing the third base to a T
d. Switching the last base from a T to an A
Misc 400

ACTTGTGCCG what type of mutation has
occurred?
a) Point mutation
b) Deletion
c) Insertion
d) There is no mutation
