Upon entering the cell, the protease enzyme produces the reverse transcriptase and ribonuclease (RNAse) H enzymes responsible for synthesizing the single-stranded DNA (ssDNA) molecules and primers necessary to produce the complementary DNA strand. Because reverse transcriptase lacks proofreading capacity, considerable base-to-base variability results. The high mutation rate, combined with the high reproductive rate, results in substantial evolution and subsequent resistance to treatment.
