What is DNA polymerase?
A. An enzyme that corrects mutations that arise during the replication of DNA
B. An enzyme that seals any gaps that remain between bases of replicating strands of DNA
C. Short, single strand of DNA that base-pairs with a specific DNA sequence
D. An enzyme that carries out DNA replication
When two adjacent bases in the same strand of DNA dimerize (form a covalent bond between them), what happens to the DNA?
a.
the original strand of DNA now contains a new DNA sequence
b.
the original strand of DNA is prevented from opening during replication, so this section of DNA will not be replicated
c.
the original strand of DNA is methylated, which causes the bases to mismatch
d.
the original strand of DNA is kinked, which prevents DNA polymerase from working properly
e.
the original strand of DNA is unaffected, so no additional mutations arise
