HIV and AIDS

2. the shape of HIV's structure
6. Part of the HIV structure that contains the genetic material (RNA) and some proteins
9. Drugs designed to inhibit the enzyme reverse transcriptase without affecting the host cell
12. The type of molecule on the cell membrane of the host helper T-cell, where the attachment protein attaches
13. Designed to target the few virus-specific enzymes(enzymes that only the virus uses) that exist
14. A more serious infection which AIDS patients are more susceptible to as the virus progresses and the number of immune system cells decreases further
15. A condition where the immune system deteriorates and eventually fails, making the person more vulnerable to other infections
16. The usual number of years between infection with HIV and the development of AIDS without treatment
18. An extra outer layer in HIV's structure, which is made of membrane stolen from the cell membrane of a previous host cell

1. A parasite infection which is often developed in the brain during the late stages of AIDS, when patients have a very low number of immune system cells
3. Used to make viral proteins from the viral DNA found within the human DNA
4. Usually infected during the initial symptoms of AIDS
5. Infected (and eventually killed) by HIV. Acts as the host cell for the virus and is the site of HIV replication
7. Kill bacteria by interfering with their metabolic reactions. They target the bacterial enzymes and ribosomes used in these reactions
8. Used to make a complementary strand of DNA from the viral RNA template
10. The genetic material released into the host cell's cytoplasm when the capsid uncoats
11. period When HIV replication drops to a lower level
17. A virus that affects the immune system and eventually leads to acquired immune deficiency syndrome(AIDS)
