Explain how a retrovirus, which has an RNA
genome, is able to integrate its genetic material into that of a hosting having a DNA genome.
Because the retroviral genome is RNA, whereas that of the host is DNA, a retrovirus must produce reverse transcriptase, an enzyme that synthesizes complementary DNA from either an RNA or a DNA template. A retrovirus uses reverse transcriptase to make a double-stranded DNA copy from its single-stranded RNA genome. The DNA copy then integrates into the host chromosome to form a provirus, which is replicated by host enzymes when the host chromosome is dublicated
