Which Enzyme is Unique to the Retro Elements

Question

Which enzyme is unique to the retro elements?
A) Reverse transcriptase
B) Reverse resolvase
C) Transposase
D) Integrase
E) Reverse integrase

Accepted Answer

Reverse transcriptase is an enzyme that is unique to retro elements, such as retroviruses and retrotransposons. This enzyme is responsible for converting the RNA genome of retroviruses and retrotransposons into DNA, which can then be inserted into the host genome. No other transposable elements or viruses use reverse transcriptase in their replication cycle.
