Question:

HIV is classified as a ...A... and its genetic material consists of ...B.... HIV replicate inside host cells and is categorized as a retrovirus due to its utilization of the enzyme ...C... to convert ...D... into ...E.... Here A to E refers to :

Options:

A–retrovirus, B–RNA, C–reverse transcriptase, D–RNA, E–DNA

A–retroviral, B–DNA, C–reverse transcriptase, D–DNA, E–RNA

A–rhinovirus, B–DNA, C–reverse transcriptase, D–DNA, E–RNA

A–adenovirus, B–RNA, C–reverse transcriptase, D–RNA, E–DNA

Correct Answer:

A–retrovirus, B–RNA, C–reverse transcriptase, D–RNA, E–DNA

Explanation:

The correct answer is Option (1) - A–retrovirus, B–RNA, C–reverse transcriptase, D–RNA, E–DNA

HIV (Human Immunodeficiency Virus) is classified as a retrovirus. It belongs to a family of viruses that replicate using a unique process called reverse transcription. Instead of having DNA as their genetic material, retroviruses like HIV have RNA as their genetic material. HIV uses an enzyme called reverse transcriptase  to convert its RNA genome into DNA inside the host cells it infects. This viral DNA is then integrated into the host cell's DNA and can be transcribed and translated to produce new virus particles.

So, the answer is: HIV is classified as a retrovirus (A) and has genetic material composed of RNA (B). HIV replicates inside the host cells. It is considered a retrovirus because it uses an enzyme called reverse transcriptase (C) to convert viral RNA (D) into DNA (E).
