Each of the following statements concerning reverse transcriptase is true EXCEPT?
A) It has been found as a component of RNA tumor viruses.
B) It can use an RNA template for the synthesis of DNA.
C) It can be used for the construction of cDNA clones from mRNA.
D) It carries out the transcription of viral_specific mRNAs.
E) It can utilize phosphorylated AZT for nucleic acid synthesis.

Question

Quizplus · Accepted Answer

Reverse transcriptase does not carry out the transcription of viral-specific mRNAs; rather, it synthesizes complementary DNA (cDNA) from an RNA template. The other statements are true - reverse transcriptase is found in RNA tumor viruses, can use an RNA template for the synthesis of DNA, can be used for the construction of cDNA clones from mRNA, and can utilize phosphorylated AZT for nucleic acid synthesis.
