To which class restriction nucleases belong?

Options

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

Answer

**Step-by-Step Text Solution:**

1. **Understanding Restriction Nucleases**:
- Restriction nucleases, also known as restriction endonucleases, are enzymes that cut DNA at specific sequences. They play a crucial role in molecular biology, particularly in the field of genetic engineering.

2. **Function of Restriction Nucleases**:
- These enzymes recognize specific nucleotide sequences in the DNA and cleave the DNA at those sites. This ability to cut DNA at precise locations is essential for various applications, including recombinant DNA technology.

3. **Classification of Enzymes**:
- Enzymes are categorized into different classes based on their functions. The relevant classes include ligases, nucleases, and oxidoreductases, among others.

4. **Identifying the Correct Class**:
- Given the options: lysis, ligases, nucleases, and oxidoreductase, we need to determine which class restriction nucleases belong to. Since restriction nucleases are involved in cutting DNA, they fall under the category of nucleases.

5. **Conclusion**:
- Therefore, restriction nucleases belong to the class of nucleases.

**Final Answer**: Restriction nucleases belong to the class of nucleases.
