`{:(Column I,Column II),(A."Taq DNA polymerase",(i)"Cleaves the ends of linear DNA"),(B."Exonuclease",(ii)"Breakdown of ungal cell wall"),(C."Protease",(iii)"Stable above" 90^(@)C),(D."Chitinase",(iv)"Made only by eukaryotic cells"),(,(v)"Degradation of proteins"):}`

Options

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

Answer

To solve the question, we will match the enzymes listed in Column I with their corresponding characteristics or activities in Column II.

### Step-by-Step Solution:

1. **Identify the enzymes in Column I:**
- A. Taq DNA polymerase
- B. Exonuclease
- C. Protease
- D. Chitinase

2. **Identify the characteristics in Column II:**
- (i) Cleaves the ends of linear DNA
- (ii) Breakdown of fungal cell wall
- (iii) Stable above 90°C
- (iv) Made only by eukaryotic cells
- (v) Degradation of proteins

3. **Match each enzyme with its characteristic:**
- **For A. Taq DNA polymerase:**
- Taq DNA polymerase is known for its stability at high temperatures, specifically above 90°C.
- **Match:** A → (iii) Stable above 90°C

- **For B. Exonuclease:**
- Exonuclease is an enzyme that cleaves nucleotides from the ends of DNA molecules.
- **Match:** B → (i) Cleaves the ends of linear DNA

- **For C. Protease:**
- Protease is an enzyme that breaks down proteins into smaller peptides or amino acids.
- **Match:** C → (v) Degradation of proteins

- **For D. Chitinase:**
- Chitinase is an enzyme that breaks down chitin, which is found in the cell walls of fungi.
- **Match:** D → (ii) Breakdown of fungal cell wall

4. **Compile the matches:**
- A → (iii) Stable above 90°C
- B → (i) Cleaves the ends of linear DNA
- C → (v) Degradation of proteins
- D → (ii) Breakdown of fungal cell wall

5. **Final Matching:**
- A: (iii)
- B: (i)
- C: (v)
- D: (ii)

6. **Select the correct answer from the given codes:**
- The correct order is:
- A is 3
- B is 1
- C is 5
- D is 2
- Therefore, the answer is option D.
