SC.912.L.16.3
1. The process of DNA replication is shown in the diagram below.
Which of the following statements best describe the role of DNA replication?
A. DNA replication is important for repairing chromosomal mutations that result in
phenotypic changes.
B. DNA replication is important for regulating the expression of genes during protein
synthesis.
C. DNA replication is important for ensuring that organisms have common ancestry.
D. DNA replication is important for transmitting and conserving genetic information.
SC.912.L.16.3
2. As a cell prepares to divide during the cell cycle, DNA replication must take place. During
the S-phase, DNA strands unwind and replication occurs along the 2 separated strands. What
happens during DNA replication?
A. During DNA replication, strands unwind to provide a template for making identical DNA
strands.
B. During DNA replication, a copy of DNA is made which is directly used as a code for
protein synthesis.
C. During DNA replication, proteins are made which are important in maintaining
homeostasis.
D. During DNA replication, copies of RNA are made so there is a continuous supply
available for transcription.

3. Which of the following best supports the statement, “The genetic code is universal and is
common to almost all organisms.”
A.
B.
C.
D.
The relationship between the processes of photosynthesis and cellular respiration.
Using recombinant bacteria to produce human insulin.
Growing cancerous cells in the laboratory.
Cloning a mouse.

4. During a laboratory exercise, Wei is asked to observe cells from different plants, animals and
bacteria. Her teacher asks her to list structures that are found in all cells. Which of the following
could most likely be found in all the cells that she studies?
A.
B.
C.
D.
cell membrane, cytoplasm, DNA
cell membrane, centrioles, DNA
cell membrane, cell wall, DNA
cell wall, cytoplasm, DNA
SC.912.L.16.4
5. If a DNA insertion of the base Cytosine (C) occurred at the point indicated by the arrow, what
would be the most likely effect? NOTE: A codon chart is provided on page 4 of this assessment.
T–A-C- G- C-C-T–A–A–A–C–T–C–C-A
A.
B.
C.
D.
The protein will not change since the insertion occurred in a stop codon.
The protein will be unchanged, since the insertion occurred in a non-coding area.
The protein will change since the insertion occurred at the end of the DNA sequence.
The protein will change since the addition of another codon, adds an additional amino
acid.
SC.912.L.16.4
6. Which of the following mutations would most likely be passed along to an organism’s
offspring?
A. Mutations that occur in both DNA strands synthesized during the S-phase of the mitotic
cell cycle.
B. Mutations that involve the translocation of chromosomes in gametes during meiosis.
C. Mutations that occur during crossing over during the prophase stage of mitosis.
D. Mutations that occur in somatic cells during cell division.

SC.912.L.16.5
7. Which of the following changes is least likely to produce a phenotypic change in an organism
and why? NOTE: A codon chart is provided on page 4 of this assessment.
A. GAU to GGU because a change in the second amino acid of a codon does not have much
effect on the protein produced.
B. AUG to AUA because as long as the first to amino acids are the same, there is little effect
on the protein produced.
C. UGA to UAA because both code for a stop codon therefore there is no effect on the
protein produced.
D. UAG to UAC because a change in the last amino acid of a codon, produces very little
change.

10. Which of the following reflects the protein synthesized from the mRNA strand shown below.
NOTE: A codon chart has been provided below.
A-U-G-C-G-C-C-A-C-U-U-A-U- A-G-A
A. The first 3 nucleotides are not a start codon, therefore, a polypeptide cannot be
synthesized.
B. There is not a complete codon at the end of the mRNA strand, so a protein is not made.
C. A – U – G – C – G – G – A – U – U – U – G – A - G – G – U
D. Met-Arg-His-Leu
