Question 5

Reverse transcriptase,the enzyme responsible for copying viral RNA into cDNA prior to integration into the host genome,lacks 3'-to-5' exonuclease "proofreading" ability.How is this advantageous to organisms that depend on such enzymes?

Accepted Answer

Retroviruses depend on reverse transcrip
