Which is incorrect descriptions of the genetic event initiated by the HIV reverse transcriptase (RT) upon the HIV infection? a. RT catalyzes initial synthesis of ssDNA using viral genomic RNA as the template.
b. The first RNA template is degraded after ssDNA synthesis.
c. The whole process is completed after synthesis of dsDNA.
d. tRNAs are adopted as the first primers.
e. None of these

e. None of these

Explanation:

The immune deficiency viruses (HIV) are retroviruses that use a reverse transcriptase (RT) enzyme to produce a single-stranded DNA (ssDNA) from an RNA template. The reverse transcription allows retroviruses to replicate their genetic material, which is integrated into the host's genome as a double-stranded linear DNA molecule in a similar way to the mechanism of insertion used by endogenous retrotransposons. The synthesis of DNA is started by cellular tRNAs (tRNA3Lys) that are packaged into the virion. After reverse transcription, the HIV DNA enters the nucleus of CD4 immune cells (also known as CD4+ T cells), and then it integrates into the genome to coopt the host's cell machinery for its own replication.
