- AHumans engaged in sexual behaviour with monkeys.
- BHumans started hunting monkeys.
- CScientists started on careless research with monkeys.
- DZoos were created, increasing monkey-human contact.
2Dr. Gottlieb is:

6Gaëtan Dugas was written about in the book 'And The Band Played On: Politics, People and the AIDS Epidemic'. He was an important figure in AIDS research because:
- AFor a long time he was mistakenly considered to be the index patient for AIDS.
- BHe was a prominent author who wrote about AIDS.
- CHe created to the first name of HIV, 'GRIDS'.
- DHe was a primary cause in the intravenous drug use transmission of HIV.
7In response to HIV, the immune system is attacked, and antibodies cannot be generated quickly. This is why from 3 weeks to 6 months an antibody test on an infected person might mistakenly turn up a:
- Afalse positive.
- Bfalse negative.
- Ctrue positive.
- Dtrue negative.
8The first symptoms of HIV within the first two weeks commonly appears to be:
- AAn acute, flu-like infection.
- BA fever that lasts several weeks.
- CDilated pupils.
- DA slight rash.
9If you want the most accurate results for if you have HIV, you should get an antibody test.
- ATrue
- BFalse
10The most common way for HIV to be transferred between mother and child is:
- ATransplacentally in the womb.
- BDuring the birth process.
- CPostnatal breast feeding.
- DUpon conception.
11Giving an HIV-positive mother a dose of HIV drugs before birth and a dose to the child up to 72 hours after birth can greatly reduce likelihood of permanent HIV infection in the child.
- ATrue
- BFalse
12Approximately what percent of all people living with AIDS live in Sub-Saharan Africa?
- A10%.
- B70%.
- C50%.
- D90%.
13In HIV, the genome is contained in:
- ATwo identical strands of RNA.
- BOne long coil of RNA.
- CDNA.
- DThere is no genome.
14In order to make DNA out of their RNA, retroviruses like HIV use an enzyme called:
- AReverse transcriptase.
- BRNAstase.
- CGenome Inverstil.
15In viral cell attachment, there are multiple steps. First, [blank_start]GP120[blank_end] must bind to two receptors to get into the host cell. Once in the cell, the virus' [blank_start]reverse transcriptase[blank_end] turns RNA into DNA. The enzyme [blank_start]integrase[blank_end] enables integration of viral DNA into cellular DNA. After this, the enzyme [blank_start]protease[blank_end] cleaves polypeptides into functional [blank_start]HIV-1 proteins[blank_end]. Lastly, the virus [blank_start]buds[blank_end] from the cell wall and leaves to infect other cells.
- AGP120
- Breverse transcriptase
- Cintegrase
- Dprotease
- Ebuds
- FHIV-1 proteins
- GmRNA
- Himmune system
16For HIV Chemotherapy, one of the treatments is HAART. HAART stands for:
- AHighly Active Anti Retroviral Therapy.
- BHIV Analysis And Removal Therapy.
- CHeavily Aggressive Antigen Resource Treatment.
- DHeat Activated Aorta Resonance Treatment.
17Inhibitors of viral enzymes can be competitive or non-competitive. With competitive inhibitors, the inhibitor:
- ALeaves substrate in the enzyme, preventing other substrate (the virus) from binding.
- BPrevent integrase from inserting viral DNA into cellular DNA.
- CCoats the outside of the cell, preventing the virus from budding out of the cell.
- DFights the viral enzymes directly.
18The HAART treatment commonly helps patients survive:
- ATo their mid 30s.
- BTo the life expectancy they would have without HIV.
- C10 years longer than they would have without HAART.
- DForever. HAART patients commonly become immortal.
19All cells will make viruses once they are infected with HIV.
- ATrue
- BFalse
20AZT is a competitive inhibitor for HIV. It stops reverse transcriptase from making viral DNA by:
- AIntegrating into the chain without a hydroxyl group, terminating the chain.
- BTaking apart the reverse transcriptase.
- CPreventing it from getting the necessary materials to make the DNA.
- DCutting the RNA into segments.
21A similar competitive inhibitor to AZT, Lamivudine was initially used for HIV patients, but found to be more effective combating:
- APertussis.
- BHepatitis B.
- CPolio.
- DAIDS.
22This drug is used for best prevention of mother to child HIV transmission, as it is very safe:
- ANevirapine.
- BLamivudine.
- CAZT.
- DIntegrase.
23In America, these are the proportion of HIV infected individuals at each stage of care.
Of all patients with HIV,
80% - [blank_start]Are diagnosed.[blank_end]
62% - [blank_start]Are linked to HIV care.[blank_end]
41% - [blank_start]Are retained in HIV care.[blank_end]
36% - [blank_start]Are on antiretroviral therapy.[blank_end]
28% - [blank_start]Have a suppressed viral load.[blank_end]- AAre diagnosed.
- BAre linked to HIV care.
- CAre retained in HIV care.
- DAre on antiretroviral therapy.
- EHave a suppressed viral load.
24HAART requires 5 years of continuous viral treatment with full adherence to eliminate HIV in the body.
- ATrue
- BFalse
25During HAART treatment, it's possible for patients to experience ARV (anti-retroviral) failure. This is most commonly caused by:
- ATreatment interruption.
- BPiranhas.
- CToo much sexual contact (protected or not).
- DDeath.
26To enter the Helper T cell, the HIV receptor must bind to two receptors:
- AFirst, CD4, then CCR5.
- BFirst, CCR5, then CD4.
- CFirst, to the nucleus, then to the plasma membrane.
- DFirst to the CD4, then to the genome.
27Timmothy Brown is a famous patient in HIV treatment because:
- AAfter a bone marrow transplant, he became HIV negative.
- BHe was the index case for HIV.
- CHis tears could heal other HIV patients.
- DHe survived to over 100 without any treatment whatsoever.
28HIV most commonly attacks Helper T cells. This is is a problem because:
- AHelper T cells are high on the immune system hierarchy, and T and B cells depend on them.
- BHelper T cells are very low on the immune system hierarchy, so it's not that much of a problem.
- CHelper T cells are at the top of the immune system hierarchy, and everything depends on them.
- DHelper T cells are coated with CCR5, an important receptor that will lead to death if suppressed.
29HIV can infect the brain if it's transported into it by this cell, which has clearance into the brain:
- AHelper T Cells.
- BMacrophages.
- CMemory B Cells.
- DPlasma Cells.
30In HIV patients, the relationship between helper T cells and antibodies is commonly as follows:
- AAntibody levels rise, and helper T cell levels rise.
- BAntibody levels rise, and helper T cell levels lower.
- CAntibody levels lower, and helper T cell levels lower.
- DAntibody levels lower, and helper T cell levels rise.
