19) identify how the haart works when used on a patient that has contracted hiv.

channels of the cell membranes. azt will interfere with the conversion of viral dna into
rna and the integrase inhibitors prevent hiv from inserting its dna into the host cell.

on the cell membranes. azt will interfere with the conversion of viral dna into rna and
the integrase inhibitors prevent hiv from inserting its dna into the host cell.
d. entry inhibitors in haart will prevent the hiv virus from binding to the cd4 receptors
on the cell membranes. azt will interfere with the conversion of viral rna into the
cellular proteins and the integrase inhibitors prevent hiv from inserting its dna into the
host cell.
