An advantage of viral DNA using LTR to produce a four-nucleotide overhang on the 3' end is to
A) start replication.
B) help with alignment of the viral DNA to the host DNA.
C) start a base mismatch repair sequence.
D) help with cell meiosis.

Question

Quizplus · Accepted Answer

The four-nucleotide overhang on the 3F1F1F1S1F1F1F10 end, produced by viral DNA using LTR, helps with the alignment of the viral DNA to the host DNA during integration. This facilitates the successful integration of the viral DNA into the host genome. The other options listed (A, C, and D) are not supported by evidence and are therefore incorrect.
