Ans.
Viruses are small obligate intracellular parasites, which by definition contain either a RNA or DNA genome surrounded by a protective, virus-coded protein coat. Viruses may be viewed as mobile genetic elements, most probably of cellular origin and characterized by a long co-evolution of virus and host. For propagation viruses depend on specialized host cells supplying the complex metabolic and biosynthetic machinery of eukaryotic or prokaryotic cells. A complete virus particle is called a virion. The main function of the virion is to deliver its DNA or RNA genome into the host cell so that the genome can be expressed (transcribed and translated) by the host cell. The viral genome, often with associated basic proteins, is packaged inside a symmetric protein capsid. The nucleic acid-associated protein, called nucleoprotein, together with the genome, forms the nucleocapsid. In enveloped viruses, the nucleocapsid is surrounded by a lipid bilayer derived from the modified host cell membrane and studded with an outer layer of virus envelope glycoproteins.

HIV is a single stranded RNA virus
HIV, or Human Immunodeficiency Virus, is a retrovirus that belongs to the family of Lentiviridae. It is known for its ability to infect and destroy the immune system's CD4 T cells, leading to acquired immunodeficiency syndrome (AIDS). Here's why HIV is classified as a single stranded RNA virus:
Genetic Material
- HIV's genetic material consists of single-stranded RNA. This RNA serves as the blueprint for producing viral proteins and replicating the virus within host cells.
- Unlike DNA viruses, which utilize double-stranded DNA as their genetic material, HIV relies on single-stranded RNA for its replication process.
Reverse Transcription
- One of the unique features of HIV is its ability to undergo reverse transcription, a process where the viral RNA is converted into DNA by the enzyme reverse transcriptase.
- This newly formed viral DNA is then integrated into the host cell's genome, allowing the virus to replicate and produce more viral particles.
Variability
- The single-stranded nature of HIV's RNA genome contributes to its high mutation rate. This leads to genetic variability within the viral population, making it challenging to develop effective vaccines or treatments.
In conclusion, HIV is classified as a single stranded RNA virus due to its genetic makeup and replication process. Understanding these characteristics is crucial for developing strategies to combat HIV and manage AIDS effectively.
