Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
HIV is an example of which type of virus?
A
Lysogenic
B
Bacterial
C
Lytic
D
None of the above
Explanation: 

Detailed explanation-1: -For instance the AIDS viruses can either infect humans (or some other primates) lytically, or lay dormant (lysogenic) as part of the infected cells’ genome, keeping the ability to return to lysis at a later time.

Detailed explanation-2: -The lambda virus ( ) is an example of a lysogenic bacteriophage. The E. coli bacteria also get infected by the lambda virus. Viruses that infect animal or plant cells can have infections where they don’t produce virions for prolonged periods of time.

Detailed explanation-3: -The lytic cycle involves the reproduction of viruses using a host cell to manufacture more viruses; the viruses then burst out of the cell. The lysogenic cycle involves the incorporation of the viral genome into the host cell genome, infecting it from within.

Detailed explanation-4: -The human immunodeficiency virus (HIV) is grouped to the genus Lentivirus within the family of Retroviridae, subfamily Orthoretrovirinae [1].
