The genetic material found in Human Immunodeficiency Virus $(HIV)$ is:

Which of the following is considered the factory for $HIV$?

In $AIDS$,the number of which type of $T$-lymphocytes decreases?

How many types of enzymes are present in the core protein of the $HIV$ virus?

Identify the correct sequence for the mechanism of $HIV$ infection:
$1.$ Viral $RNA$ replicates to form viral $DNA$ with the help of reverse transcriptase.
$2.$ The progeny viruses released in the blood attack other $T_H$ cells and destroy them.
$3.$ Viral $DNA$ gets incorporated into the host cell's $DNA$ and produces virus particles.
$4.$ Virus enters into macrophages.

Human immune deficiency virus $(HIV)$ is a retrovirus with centrally located two $ssRNA$ molecules. It is covered by an outer layer of $I$ protein and an inner layer made up of $II$ protein.
