Match column I with II column II and select the correct option from the given codes .
`{:("Column I","Column II"),(A."Griffith",(i)"Lac operon"),(B."Hershey and Chase",(ii)"Semi-conservative DNA replication"),(C."Meselson",(iii)"Transduction"),(D."Jacob and Monod",(iv)"Transformation"):}`

Options

A. A-(iv),B-(iii),C-(ii),D-(i)
B. A-(iii),B-(iv),C-(ii),D-(i)
C. A-(iv),B-(ii),C-(iii),D-(i)
D. A-(ii),B-(i),C-(iii),D-(iv)

Answer

To solve the matching question, we need to connect each scientist from Column I with their corresponding discovery from Column II. Here’s the step-by-step solution:

### Step 1: Identify the contributions of each scientist
1. **Griffith**: Known for his transformation experiment with mice, which demonstrated that a non-virulent strain of bacteria could be transformed into a virulent strain.
2. **Hershey and Chase**: Conducted experiments that provided evidence that DNA is the genetic material, using bacteriophages in their studies. Their work is associated with the concept of transduction.
3. **Meselson and Stahl**: Conducted the famous experiment that demonstrated the semi-conservative nature of DNA replication using heavy isotopes of nitrogen.
4. **Jacob and Monod**: Known for their work on the lac operon, which is a model for understanding gene regulation in prokaryotes.

### Step 2: Match each scientist with the correct discovery
- **A. Griffith** matches with **(iv) Transformation**.
- **B. Hershey and Chase** matches with **(iii) Transduction**.
- **C. Meselson** matches with **(ii) Semi-conservative DNA replication**.
- **D. Jacob and Monod** matches with **(i) Lac operon**.

### Step 3: Write the final matches
- A → (iv) Transformation
- B → (iii) Transduction
- C → (ii) Semi-conservative DNA replication
- D → (i) Lac operon

### Final Answer
The correct matches are:
- A → (iv)
- B → (iii)
- C → (ii)
- D → (i)
