試題詳解

6. Which of the following statements are true for the enzyme reverse transcriptase?
(A) It is sensitive to high temperatures and so can be readily "killed" by heat treatment when the reaction is completed.
(B) It does not require a primer to initiate polymerization as do most DNA polymerases.
(C) It is insensitive to high temperatures and so can survive the many cycles of heating required to perform the polymerase chain reaction.
(D) It is an RNA-dependent DNA polymerase.
(E) It lacks the proofreading function of most DNA polymerases and so is able to utilize mRNA from mutated genes as a template.
