These days, antisense oligodeoxynucleotides (ASOs) are underneath investigation as new medications accustomed to halt HIV an infection.

Bonhoeffer et al.[84] prompt that template switching by reverse transcriptase functions to be a fix system to cope with breaks in The only-stranded RNA genome. Furthermore, Hu and Temin[eighty] suggested that recombination is really an adaptation for mend of harm from the RNA genomes. Strand switching (duplicate-alternative recombination) by reverse transcriptase could create an undamaged duplicate of genomic DNA from two harmed single-stranded RNA genome copies. This view of your adaptive benefit of recombination in HIV could clarify why Just about every HIV particle consists of two entire genomes, in lieu of just one.
