Central dogma of molecular biology was proposed by

Options

A. F. Crick
B. H. Temin
C. D. Baltimore
D. M. Wilkins

Answer

**Step-by-Step Solution:**

1. **Understanding the Central Dogma**: The central dogma of molecular biology describes the flow of genetic information within a biological system. It outlines how DNA is replicated, transcribed into mRNA, and then translated into proteins.

2. **Identifying the Key Processes**:
- **Replication**: The process by which DNA makes a copy of itself.
- **Transcription**: The process where the information in DNA is transferred to mRNA.
- **Translation**: The process where mRNA is used to synthesize proteins.

3. **Recognizing the Scientist**: The central dogma was proposed by Francis Crick in 1957. He is also known for co-discovering the structure of DNA.

4. **Evaluating the Options**:
- **Francis Crick**: Correct, as he proposed the central dogma.
- **H. Tamim**: Incorrect, not known for this contribution.
- **D. Baltimore**: Incorrect, although he contributed to molecular biology, he did not propose the central dogma.
- **M. Wilkins**: Incorrect, known for his work on DNA but not for proposing the central dogma.

5. **Conclusion**: The correct answer is **Francis Crick**.

**Final Answer**: Francis Crick
