Enzyme reverse transcriptase is also known as :

Options

A. DNA dependent RNA polymerase
B. RNA dependent RNA polymerase
C. RNA dependent DNA polymerases
D. DNA dependent DNA polymease

Answer

To solve the question "Enzyme reverse transcriptase is also known as:", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Reverse Transcriptase**:
- Reverse transcriptase is an enzyme that synthesizes DNA from an RNA template. This process is known as reverse transcription.

2. **Identifying Related Processes**:
- In molecular biology, there are several key processes involving enzymes:
- **Replication**: The process of copying DNA, which involves the enzyme DNA polymerase.
- **Transcription**: The process of synthesizing RNA from DNA, which involves the enzyme RNA polymerase.
- **Reverse Transcription**: The process of synthesizing DNA from RNA, which involves reverse transcriptase.

3. **Naming the Enzyme**:
- Reverse transcriptase is specifically known for converting RNA back into DNA.
- It is also referred to by other names that describe its function:
- **RNA-Directed DNA Polymerase**: This name highlights that it uses RNA as a template to synthesize DNA.
- **RNA-Dependent DNA Polymerase**: This name emphasizes that the enzyme is dependent on RNA to carry out the synthesis of DNA.

4. **Conclusion**:
- Therefore, reverse transcriptase is also known as RNA-Directed DNA Polymerase or RNA-Dependent DNA Polymerase.

### Final Answer:
Reverse transcriptase is also known as RNA-Directed DNA Polymerase or RNA-Dependent DNA Polymerase.
