Match the terms given in column I with their definitions in column II and select the correct answer from codes given below.
`{:(Column I,Column II),(A."Transformation",(i)"Sequences cut by restriction enzymes"),(B."Recognition site",(ii)"Process by which DNA fragments are separated based on their size"),(C."Gel electrophoresis",(iii)"Plasmid DNA that has incorporated human DNA"),(D."Recombinant DNA",(iv)"Process by which bacteria take up pieces of DNA from the environment"):}`

Options

A. 1) `A-(iii),B-(i),C-(ii),D-(iv)`
B. 2) `A-(iv),B-(i),C-(ii),D-(iii)`
C. 3) `A-(i),B-(ii),C-(iii),D-(iv)`
D. 4) `A-(ii),B-(iii),C-(iv),D-(i)`

Answer

To solve the matching question, we need to identify the correct definitions for each term in Column I based on the descriptions provided in Column II. Let's go through each term step by step.

### Step-by-Step Solution:

1. **Identify the term "Transformation" (A)**:
- **Definition**: Transformation refers to the process by which bacteria take up pieces of DNA from the environment.
- **Match**: This corresponds to definition (iv).
- **Result**: A → (iv)

2. **Identify the term "Recognition site" (B)**:
- **Definition**: Recognition sites are specific sequences in DNA where restriction enzymes cut.
- **Match**: This corresponds to definition (i).
- **Result**: B → (i)

3. **Identify the term "Gel electrophoresis" (C)**:
- **Definition**: Gel electrophoresis is a technique used to separate DNA fragments based on their size.
- **Match**: This corresponds to definition (ii).
- **Result**: C → (ii)

4. **Identify the term "Recombinant DNA" (D)**:
- **Definition**: Recombinant DNA is plasmid DNA that has incorporated human DNA.
- **Match**: This corresponds to definition (iii).
- **Result**: D → (iii)

### Summary of Matches:
- A → (iv)
- B → (i)
- C → (ii)
- D → (iii)

### Final Answer:
The correct matches correspond to option number 2, which includes:
- A → (iv)
- B → (i)
- C → (ii)
- D → (iii)
