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 Processes**: The central dogma consists of three main processes:
- **Replication**: The process by which DNA makes a copy of itself.
- **Transcription**: The process of synthesizing mRNA from a DNA template.
- **Translation**: The process of synthesizing proteins based on the sequence of the mRNA.

3. **Historical Context**: The concept of the central dogma was proposed in 1953, a pivotal year in molecular biology.

4. **Attributing the Discovery**: The central dogma was proposed by **Francis Crick**, who, along with James Watson, is credited with discovering the structure of DNA.

5. **Conclusion**: Therefore, the correct answer to the question "Central dogma of molecular biology was proposed by" is **Francis Crick**.
