What happens when HIV infects a person?
What happens when HIV infects a person?
- The patient's body becomes resistant to other viruses.
- The immune system of the patient becomes stronger.
- HIV destroys the genetic material of the host cell and replaces it with its own genetic material.
- HIV causes the patient's immune system to shut down. (correct)

Study Notes
Viruses
- Viruses are not living organisms
- Characteristics of viruses include:
- They can only replicate inside host cells
- They are obligate intracellular parasites
- They can infect all types of life forms
Human Immunodeficiency Virus (HIV)
- The main target of HIV is the immune system's CD4 cells (T cells)
- When HIV infects a person, it destroys T cells, weakening the immune system
- HIV infects host cells and takes over their genetic material
- HIV replicates its own genetic material instead of the host cell's DNA/RNA, a process known as transcription
Viral Replication
- The process of viral replication is called transcription
- In transcription, the virus's genetic material is replicated instead of the host cell's DNA/RNA
