A)Viral reverse transcriptase uses viral RNA to make double-stranded viral DNA.
B)Viral reverse transcriptase uses viral single-stranded DNA to make double-stranded viral DNA.
C)Viral reverse transcriptase uses viral RNA to make double-stranded viral RNA.

E)Host enzymes convert viral RNA to double-stranded viral DNA.

Question

Quizplus · Accepted Answer

Retroviruses use reverse transcriptase to make a copy of their RNA genome into double-stranded DNA, which is then integrated into the host cell genome. This process involves making a single-stranded DNA intermediate that is then used to make the double-stranded DNA form. Therefore, viral reverse transcriptase uses viral RNA to make double-stranded viral DNA.
