Azidothymidine (AZT) is an HIV drug. AZT is a reverse transcriptase inhibitor. That means AZT is only effective during the __________ stage of the viral life cycle. - correct answer Entry Which virus uses reverse transcriptase in its reproductive cycle? - correct answer HIV A _______ uses the lytic cycle to begin the immediate manufacture of new phages in the host cells. - correct answer ...

ART - correct answer anti-retroviral therapy: not a cure, but controls virus and prevents transmission to others; prevents HIV virus from making copies of itself; the less HIV in your body, the better the chance for your immune system to recover (can fight off opportunistic infections); drug combinations, number of ARVs success--drop in viral load below level of detectability issues--not always effective, uncertainty of duration of effectivenes...
