HIV is what
1. An emerging virus
2. A bacteriophage
3. A prion
4. A prophage
The correct answer is 1. An emerging virus. HIV, which stands for Human Immunodeficiency Virus, is a virus that causes HIV infection and leads to AIDS (Acquired Immunodeficiency Syndrome). It is considered an emerging virus because it was first identified in the 1980s and has since become a global epidemic, affecting millions of people worldwide.
HIV (Human Immunodeficiency Virus) is not any of the options listed.
HIV is a virus, specifically a member of the retrovirus family, which means it is an RNA virus that replicates using the enzyme reverse transcriptase to convert its RNA genome into DNA. HIV primarily infects immune cells called CD4+ T cells, gradually weakening the immune system and leading to acquired immunodeficiency syndrome (AIDS).
