What is the genetic material found in Human Immunodeficiency Virus (HIV)?

Single-stranded RNA

The correct answer is Option (2) - Single-stranded RNA.

Human Immunodeficiency Virus (HIV) is a retrovirus that contains single-stranded RNA as its genetic material. Retroviruses, including HIV, have an RNA genome instead of DNA. The RNA genome of HIV serves as a template for the synthesis of viral DNA through the process of reverse transcription. Once the viral RNA is reverse transcribed into DNA, it integrates into the host cell's DNA and becomes a permanent part of the host genome.

Option (1) Double-stranded RNA is incorrect. While some viruses have double-stranded RNA genomes, HIV is not one of them.

Option (3) Double-stranded DNA is incorrect. Although the viral RNA is reverse transcribed into DNA, the genetic material of HIV is not double-stranded DNA.

Option (4) Single-stranded DNA is incorrect. HIV does not possess single-stranded DNA as its genetic material.

Therefore, the most appropriate answer is (2) Single-stranded RNA, which reflects the genetic material found in HIV.
