Enzymes which bring about lysis of DNA/RNA are

Options

A. Ligases
B. Lyases
C. Peptidases
D. Nucleases

Answer

**Step-by-Step Solution:**

1. **Understanding the Term 'Lysis':**
- Lysis refers to the disintegration or breaking down of a cell or its components. In the context of DNA or RNA, it means the breakdown of these nucleic acids.

2. **Identifying the Enzymes:**
- We need to identify which enzymes are responsible for the lysis of DNA or RNA.

3. **Evaluating the Options:**
- **Option A: Lysis** - This term itself does not refer to an enzyme; therefore, it cannot be correct.
- **Option B: Lysis** - This is a repetition of the first option and is also not an enzyme, making it incorrect.
- **Option C: Peptidase** - Peptidases are enzymes that break down peptides into amino acids, not nucleic acids. Hence, this option is also incorrect.
- **Option D: Nucleases** - Nucleases are enzymes that cleave the chains of nucleotides in DNA or RNA, leading to their lysis. This makes nucleases the correct answer.

4. **Conclusion:**
- Based on the evaluation of the options, the enzymes that bring about the lysis of DNA or RNA are called **nucleases**.

**Final Answer:** Nucleases
