The reverse flow of the genetic information or central dogma was discovered by:
a) Wilkins
b) Francis Crick
c) Temin and Baltimore
d) James watson

Options

A. Welkins
B. Francis Crick
C. Temin and Baltimore
D. James watson

Explanation

To determine who discovered the reverse flow of genetic information, also known as the reverse transcription process, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Central Dogma of Molecular Biology**:
- The central dogma describes the flow of genetic information within a biological system. It typically follows the pathway: DNA → RNA → Protein. This means that DNA is transcribed into RNA, which is then translated into proteins.

2. **Identify the Reverse Flow**:
- The reverse flow of genetic information refers to the process where information flows from protein back to RNA and then to DNA. This is the opposite of the traditional central dogma.

3. **Research Key Discoveries**:
- The reverse flow of genetic information was discovered through the study of retroviruses, which can convert their RNA back into DNA using an enzyme called reverse transcriptase.

4. **Evaluate the Options**:
- a) Wilkins: Known for his work on X-ray diffraction images of DNA.
- b) Francis Crick: Known for co-discovering the structure of DNA but not for reverse transcription.
- c) Temin and Baltimore: Recognized for their discovery of reverse transcriptase and the process of reverse transcription.
- d) James Watson: Also known for co-discovering the structure of DNA.

5. **Select the Correct Answer**:
- Based on the evaluations, the correct answer is **c) Temin and Baltimore**, as they were the scientists who discovered the reverse flow of genetic information.

### Final Answer:
**c) Temin and Baltimore**
