What is HIV? HIV (human immunodeficiency virus) is a virus that attacks the body's immune system. If HIV is not treated, it can lead to AIDS (acquired immunodeficiency syndrome).
What organism does HIV infect?
HIV infects the immune system, causing progressive damage and eventually making it unable to fight off infections. The virus attaches itself to immune system cells called CD4 lymphocyte cells, which protect the body against various bacteria, viruses and other germs.
Is HIV a virus or cell?
HIV is a retrovirus, which means it carries single-stranded RNA as its genetic material rather than the double-stranded DNA human cells carry. Retroviruses also have the enzyme reverse transcriptase, which allows it to copy RNA into DNA and use that DNA "copy" to infect human, or host, cells.
Is HIV a bacteria virus or fungi?
Common forms: Viruses cause colds and flus, as well as more serious conditions such as HIV/AIDS, Ebola and COVID-19.
Is virus a living organism?
Most biologists say no. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Is a virus a microorganism?
The study of microorganisms is called microbiology. Microorganisms can be bacteria, fungi, archaea or protists. The term microorganisms does not include viruses and prions, which are generally classified as non-living.
What's the difference between a virus and bacteria?
On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive.
