Which of the following process is related to reverse transcription?

Options

A. DNA dependent DNA synthesis
B. RNA dependent DNA synthesis
C. DNA dependent RNA synthesis
D. RNA dependent polypeptide synthesis

Answer

To solve the question "Which of the following processes is related to reverse transcription?", we will follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Transcription**:
- Transcription is the process where DNA is used as a template to synthesize RNA. This is a fundamental biological process that occurs in all living cells.

2. **Define Reverse Transcription**:
- Reverse transcription is the opposite of transcription. Instead of synthesizing RNA from DNA, reverse transcription involves synthesizing DNA from RNA. This process is crucial in certain viruses, such as retroviruses.

3. **Identify the Key Term**:
- The key term here is "reverse transcription," which indicates that we are looking for a process that involves RNA being converted back into DNA.

4. **Analyze the Given Options**:
- **DNA dependent DNA synthesis**: This process involves synthesizing DNA from a DNA template, which is not related to reverse transcription.
- **RNA dependent DNA synthesis**: This process involves synthesizing DNA from an RNA template, which directly corresponds to reverse transcription.
- **DNA dependent RNA synthesis**: This is the standard transcription process, where RNA is synthesized from DNA, and is not related to reverse transcription.
- **RNA dependent polypeptide synthesis**: This refers to translation, where RNA is used to synthesize proteins, and is also not related to reverse transcription.

5. **Select the Correct Answer**:
- Based on the analysis, the correct process related to reverse transcription is **RNA dependent DNA synthesis**.

### Final Answer:
The process related to reverse transcription is **RNA dependent DNA synthesis**.
