Alec J. Jeffreys discovered the fundamental technique involved in DNA finger printing, while he was studying the gene for

Options

A. dystrophin
B. myoglobin
C. haemoglobin
D. tubulin

Answer

**Step-by-Step Text Solution:**

1. **Identify the Scientist and Context**: The question refers to Alec J. Jeffreys, who is known for discovering the technique of DNA fingerprinting. This technique has significant applications in forensic science, paternity testing, and genetic identification.

2. **Understand the Focus of Alec J. Jeffreys' Research**: While developing the DNA fingerprinting technique, Jeffreys was studying a specific gene. The options provided are dystrophin, myoglobin, hemoglobin, and tubulin.

3. **Analyze the Options**:
- **Dystrophin**: A protein associated with muscular dystrophy, but not directly linked to Jeffreys' work.
- **Myoglobin**: A protein found in muscle tissue that binds oxygen, which is relevant to Jeffreys' research.
- **Hemoglobin**: The oxygen-carrying protein in red blood cells, but not the focus of Jeffreys' study.
- **Tubulin**: A protein that makes up microtubules, not related to Jeffreys' work.

4. **Conclude the Correct Answer**: After analyzing the options, it is determined that Alec J. Jeffreys was studying the gene for **myoglobin** when he discovered the fundamental techniques involved in DNA fingerprinting.

5. **Summarize the Importance**: Jeffreys' discovery of DNA fingerprinting has revolutionized forensic science and has become a crucial tool for identifying individuals based on their unique DNA profiles.

**Final Answer**: Alec J. Jeffreys discovered the fundamental technique involved in DNA fingerprinting while studying the gene for **myoglobin**.
