Which strand is complementary to a DNA
segment with bases GACTGCTTA?
A. AGTCATCCG
B. GACTGCTTA
C. ATTCGTCAG
D. CTGACGAAT
Why is it important for the weak hydrogen
bonds to hold the nitrogen bases of
complimentary DNA strands together?
A. so that bonds break for translation to occur
B. so that bonds break for DNA replication to
occur
C. so that DNA can twist to form the double
helix shape
D. so that DNA can be strengthened by another
bond during DNA replication
What aspect of DNA replication allows it to be
considered a semi-conservative process?
A. DNA replication occurs at an extremely slow
rate.
B. DNA replication only duplicates nucleotides in
pairs.
C. Each replicated strand of DNA is an old strand
paired with a new strand.
D. Each replicated strand of DNA is an identical
match with no variations.
What is the relationship between genes and
proteins?
A. Genes are made of proteins.
B. Proteins are made of genes.
C. Genes code for the making of proteins.
D. Proteins code for the making of genes.
Which best describes the correct sequence of
events that lead to the synthesis of a protein?
A. DNA is duplicated, tRNA leaves
B. RNA is copied, DNA leaves nucleus, protein is
made
C. DNA is copied into two strands, mRNA leaves
nucleus
D. DNA is copied in mRNA, leaves nucleus, lands
on a ribosome to begin translation
A segment of mRNA has the base sequence
UGUCAAACUCGA. What is the base sequence of
the original DNA segment?
A. ACAGUUUGAGCU
B. TCTGUUUGAGCU
C. ACAGTTTGAGCT
D. GAGTCCCTGTAC
How does DNA help to form proteins?
A. It creates proteins using nucleotides.
B. It forms the bonds between amino acids.
C. It creates reactants for proteins to be made.
D. It gives instructions on the amino acid
sequence.
Cells located in the skin of a frog have certain
functions that are very different from the cells
located in the liver of the frog. Which best explains
these differences?
A. The genetic material found in the skin cells and
the liver cells are different.
B. The genetic material function differently in the
skin cells and the liver cells.
C. Environmental factors can affect the liver cells,
while the skin cells are unaffected.
D. Skin cells develop through mitosis, while liver
cells develop through meiosis.
All normal body cells have the same genetic
structure. However, not all body cells have the
same function. What best explains this difference in
function?
A. Some DNA mutates as the cells are developing.
B. Some DNA functions in males, while other DNA
functions only in females.
C. Some DNA is active in certain cells, while other
DNA is active in other cells.
D. Some DNA recombines to form different proteins
than the DNA found in the original cells.
Which explains metastasis?
A. the expression of the ras gene
B. the synthesis of protein in the cell
C. the mutation of cells on the oncogene
D. the spread of malignant cells beyond the
original site
