Question

RNA retroviruses such as HIV discharge both strands of RNA and molecules of reverse transcriptase into cells they infect. What is the purpose of the reverse transcriptase?

a. The host cells rapidly destroy the viral RNA so more must constantly be made.

b. The host cells lack enzymes that can replicate the viral genome.

c. The reverse transcriptase is required to translate viral mRNA into proteins.

d. The reverse transcriptase binds to active sites of the lytic enzymes of the host cells.

Answer 1

Correct answer (b) host cell lack enzyme that can. Replicate the viral genome

Explanation:-

Reversetranscriptase:-(RNA-dependent DNA polymerase):--
It is an enzyme used to generate complementary DNA (cDNA) from an RNA template, a process termed reverse transcription. It is mainly associated with retroviruses e.g. HIV
