Nucleic acid that behave like enzymes are known as :

Options

A. Ribozyme
B. Zymogen
C. Collagen
D. Isomerase

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a specific type of nucleic acid that functions like an enzyme.

2. **Identifying the Options**: The options given are:
- A) Ribozyme
- B) Zymogen
- C) Collagen
- D) Isomerase

3. **Analyzing Each Option**:
- **Ribozyme**: This is a type of RNA that can act as an enzyme. It catalyzes biochemical reactions, similar to protein enzymes.
- **Zymogen**: This is an inactive precursor of an enzyme and is not a nucleic acid.
- **Collagen**: This is a protein, not a nucleic acid.
- **Isomerase**: This is a class of enzymes that facilitate the conversion of one isomer to another, but it is not a nucleic acid.

4. **Selecting the Correct Answer**: Based on the analysis, the only option that is a nucleic acid and behaves like an enzyme is **Ribozyme**.

5. **Conclusion**: Therefore, the correct answer to the question is **Ribozyme**.
