Which is not correctly matched ?

Options

A. Lipase - Hydrolysis of fats
B. Isomerases - Joining of similar substrate and management of substrate
C. Polymerase- chain elongation
D. DNA ligase - joins the DNA strand together by catalyzing the formation of phosphoester bonds.

Answer

To determine which option is not correctly matched, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Analyze Option 1: Lipase**
- Lipase is an enzyme that catalyzes the hydrolysis of fats into fatty acids and glycerol.
- Since it correctly describes the function of lipase, this option is **correctly matched**.

2. **Analyze Option 2: Isomerases**
- Isomerases are enzymes that convert a molecule from one isomer to another.
- The statement in the option suggests that isomerases join similar substrates and do substrate management, which is incorrect.
- Therefore, this option is **not correctly matched**.

3. **Analyze Option 3: Polymerase**
- Polymerase is an enzyme that synthesizes long chains of nucleic acids through a process called chain elongation.
- The description provided matches the function of polymerase, making this option **correctly matched**.

4. **Analyze Option 4: DNA Ligase**
- DNA ligase is an enzyme that catalyzes the joining of DNA strands by forming phosphodiester bonds.
- This description accurately reflects the function of DNA ligase, so this option is also **correctly matched**.

### Conclusion:
After analyzing all the options, we find that **Option 2 (Isomerases)** is the only one that is not correctly matched.

### Final Answer:
The option that is not correctly matched is **Option 2: Isomerases**.
