Answer:
AZT inhibits reverse transcriptase enzyme.
Explanation:
AZT inhibits reverse transcriptase enzyme that is used by the virus to make a DNA copy of its RNA. This Azidothymidine prevent reverse transcriptase enzyme from doing its function properly. Due to absence of this enzyme, the HIV virus is unable to make copies of its DNA and this Azidothymidine stops the life cycle of the virus and slows the growth of AIDS disease so that's why this drug was considered effective against HIV virus and used in the treatment of AIDS disease.
