Which enzyme found in HIV allows a DNA copy of the viral RNA to be produced within the host cell?
A
DNA polymerase
B
Integrase
C
Reverse transcriptase
D
RNA polymerase
Verified step by step guidance1
Understand the context: HIV is a retrovirus, which means it has RNA as its genetic material and needs to convert this RNA into DNA to integrate into the host's genome.
Identify the process: The conversion of viral RNA into DNA is known as reverse transcription.
Recognize the enzyme: The enzyme responsible for reverse transcription is called reverse transcriptase.
Differentiate from other enzymes: DNA polymerase synthesizes DNA from a DNA template, integrase incorporates viral DNA into the host genome, and RNA polymerase synthesizes RNA from a DNA template.
Conclude: Reverse transcriptase is the enzyme that allows a DNA copy of the viral RNA to be produced within the host cell.
