The following steps occur during multiplication of retroviruses. Which is the fourth step?
A) penetration
B) uncoating
C) synthesis of double- stranded DNA
D) attachment
E) synthesis of +RNA

Question

Quizplus · Accepted Answer

The fourth step in retrovirus multiplication is synthesis of double-stranded DNA from the viral RNA genome, which occurs after the virus has entered the host cell (attachment), penetrated the cell membrane, and undergone uncoating. Synthesis of +RNA occurs later in the life cycle, after the double-stranded DNA has integrated into the host cell's genome.
