Pol (HIV)
Pol (DNA polymerase) refers to a gene in retroviruses, or the protein produced by that gene.
The Gag-Pol region containing the protease gene flanked by p6pol at the N-terminus and reverse transcriptase at the C-terminus.
Products of pol include:
Reverse transcriptase
Common to all retroviruses, this enzyme transcribes the viral RNA into double-stranded DNA.
Integrase
This enzyme integrates the DNA produced by reverse transcriptase into the host's genome.
Protease
A protease is any enzyme that cuts proteins into segments. HIV's gag and pol genes do not produce their proteins in their final form, but as larger combination proteins; the specific protease used by HIV cleaves these into separate functional units. Protease inhibitor drugs block this step.

gollark: LyricLy should really be banned from participating if they're going to keep accessing this kind of information.
gollark: ALL of which are mine.
gollark: No you don't.
gollark: Yes you are, actually, when I win.
