What does the reverse transcriptase use as a primer to synthesize DNA?

the regulatory regions within the viral RNA genome

tRNA molecule

long-terminal repeat (LTR) sequences

a DNA molecule

a DNA-RNA hybrid molecule

Correct.

Incorrect.

Try Again.

How do the viral RNA and synthesized double-stranded DNA molecules differ in their sequences?

The DNA contains long-terminal repeats (LTR) at both ends.

The DNA contains regulatory sequences that regulate the synthesis of the DNA copy.

The RNA contains a coding region.

The RNA contains gag, pol, and env sequences.

All of the above are correct.

Correct.

Incorrect.
