Choose the wrong statement:

Options

A. Time lag between infection and appearance of AIDS is a few hours to a week
B. HIV has RNA as genetic material
C. HIV replicates in T lymphocytes
D. ARV drugs are only partially effective in AIDS treatment

Answer

To solve the question of choosing the wrong statement regarding AIDS, we will analyze each of the provided statements step by step.

### Step-by-Step Solution:

1. **Understanding AIDS and HIV**:
- AIDS (Acquired Immunodeficiency Syndrome) is caused by the Human Immunodeficiency Virus (HIV).
- HIV attacks the immune system, specifically targeting T-lymphocytes (T-helper cells).

**Hint**: Remember that AIDS is a condition resulting from the infection with HIV.

2. **Evaluating the First Statement**:
- The first statement claims that the time lag between HIV infection and the appearance of AIDS is a few hours to a week.
- This is incorrect. The window period, which is the time between infection and the appearance of detectable antibodies, typically lasts from 2 to 12 weeks.

**Hint**: Focus on the definition of the window period and its duration in relation to HIV.

3. **Evaluating the Second Statement**:
- The second statement mentions that HIV has RNA as genetic material.
- This is true, as HIV is a retrovirus with single-stranded RNA.

**Hint**: Recall that retroviruses are characterized by having RNA as their genetic material.

4. **Evaluating the Third Statement**:
- The third statement states that HIV replicates in T-lymphocytes.
- This is also true, as HIV specifically infects and replicates within T-helper cells.

**Hint**: Think about the role of T-lymphocytes in the immune system and how HIV targets them.

5. **Evaluating the Fourth Statement**:
- The fourth statement claims that ARV (Anti-Retroviral) drugs are only partially effective in treating HIV.
- This is true because ARV drugs help to slow down the replication of the virus but do not eliminate it from the body.

**Hint**: Consider the mechanism of action of ARV drugs and their limitations in treating HIV.

6. **Conclusion**:
- After evaluating all the statements, the first statement is the only incorrect one, as it misrepresents the duration of the window period for HIV.

### Final Answer:
The wrong statement is the first one regarding the time lag between HIV infection and the appearance of AIDS.
