HIV is a spherical , enveloped virus of about 90-120 nm diameter. Its nucleocapsid is icosahedral and its genome consists of a single-stranded RNA filament segmented into two identical filaments and associated with a "reverse transcriptase enzyme".

The genetic material of HIV is single-stranded RNA.
Structure of HIV
HIV is a retrovirus that infects human immune cells. It consists of a protein coat, called a capsid, and an envelope derived from the host cell membrane. Inside the capsid is the viral genome, which is composed of RNA instead of DNA.
Genetic Material of HIV
The RNA genome of HIV is single-stranded, meaning that it consists of a single chain of nucleotides. It is also positive-sense, meaning that it can be directly translated into viral proteins by the host cell machinery.
Life Cycle of HIV
Once HIV enters a host cell, it uses its reverse transcriptase enzyme to convert its RNA genome into DNA. This DNA is then integrated into the host cell genome, where it can be transcribed and translated into new viral particles. This life cycle is unique to retroviruses like HIV, which use RNA as their genetic material.
Conclusion
In conclusion, HIV has a protein coat and a single-stranded RNA genome. This unique structure allows it to infect and replicate within human immune cells, leading to the progression of AIDS.

HIV has single stranded rna that undergoes reverse transcription to form double stranded dna. this gets Incorporated into human dna and directs the cell (macrophage) to produce vital particles .
