Question 3

What would be the result if DNA polymerase did not have the ability to proofread?

Accepted Answer

A) DNA replication would not proceed at all. 
B) DNA replication would proceed more slowly.

Question 4

A rapidly dividing cell is exposed to a chemical that converts the bond that forms between adenine and thymine to a covalent bond. Which of the following is most likely to occur?

Accepted Answer

A) DNA replication would produce two molecules of DNA with mutations at every base that once held an A-T base pair. 
B) DNA replication would not occur because the two nucleotide strands that make up the DNA molecule would not be able to separate. 
C) DNA replication would occur more slowly because DNA repair proteins would have to fix the covalent bonds before replication could begin. 
D) DNA replication would be faster because covalent bonds require less energy to break than hydrogen bonds.
