Select the correct match:

Options

A. Alec Jeffreys - Streptococcus pneumoniae
B. Francois Jacob and Jacques Monod - Lac operon
C. Matthew Meselson and F. Stahl - Pisum sativum
D. Alfred Hershey and Martha Chase - TMV

Answer

To solve the question "Select the correct match," we need to analyze the information provided about various scientists and their contributions to biology. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the Scientists and Their Work
We need to look at the names of the scientists mentioned and what they are known for. The question implies that we have to match scientists with their correct discoveries or contributions.

### Step 2: Evaluate Each Scientist
1. **Alec Jeffreys**: The transcript states that Alec Jeffreys is associated with DNA fingerprinting, not with Streptococcus pneumoniae. Therefore, any match that suggests he worked on Streptococcus pneumoniae is incorrect.

2. **Lactopyrone**: The transcript mentions that Lactopyrone is correct in the context of enzymes produced by microorganisms. This suggests that there is a valid match here, but we need to confirm which scientist is associated with it.

3. **Alfred Hershey and Martha Chase**: The transcript indicates that they proved DNA is the genetic material, not proteins, and did not work on Tobacco Mosaic Virus (TMV). This indicates that any match suggesting they worked on TMV is incorrect.

### Step 3: Determine the Correct Match
From the analysis:
- Alec Jeffreys is correctly matched with DNA fingerprinting.
- The mention of Lactopyrone seems to be correct but needs to be linked to the right scientist.
- Alfred Hershey and Martha Chase are correctly associated with the discovery of DNA as genetic material.

### Conclusion
Based on the information provided in the transcript, the correct match is:
- Alec Jeffreys - DNA fingerprinting technique.

### Final Answer
The correct match is Alec Jeffreys with DNA fingerprinting.
