HIV is a number of a group of viruses called

Options

A. Bacteriophages
B. Geminiviruses
C. Lysogenic viruses
D. Retroviruses

Answer

To solve the question "HIV is a member of a group of viruses called," we can follow these steps:

### Step 1: Understand the Question
The question asks us to identify the group of viruses to which HIV belongs.

### Step 2: Analyze the Options
We have four options to consider:
1. Bacteriophages
2. Gemini viruses
3. Lysogenic viruses
4. Retroviruses

### Step 3: Define Each Option
- **Bacteriophages**: These are viruses that specifically infect bacteria. They are not related to HIV.

- **Gemini viruses**: This group consists of plant viruses that contain single-stranded DNA. They do not include HIV, which affects humans.

- **Lysogenic viruses**: These viruses can replicate through both lytic and lysogenic cycles. While they can infect cells, they do not specifically refer to HIV.

- **Retroviruses**: This group of viruses uses RNA as their genetic material. When they infect a host cell, they convert their RNA into DNA, which is then integrated into the host's genome. HIV is a well-known retrovirus that causes AIDS.

### Step 4: Identify the Correct Answer
Based on the definitions and characteristics of each option, HIV is classified as a retrovirus. Therefore, the correct answer is **retroviruses**.

### Final Answer
HIV is a member of a group of viruses called **retroviruses**.
