Which enzyme is use for removal of RNA molecule in DNA isolation process.

Answer

**Step-by-Step Solution:**

1. **Understanding the Context**: The question asks about the enzyme used to remove RNA during the DNA isolation process. DNA isolation typically involves breaking down cellular components to extract DNA.

2. **Identifying the Enzymes Involved**: In the DNA isolation process, various enzymes are used to break down different cellular components. For RNA removal specifically, we need to focus on enzymes that target RNA.

3. **Recognizing the Correct Enzyme**: The enzyme specifically used for the removal of RNA is called **ribonuclease**. This enzyme is also referred to as **RNase**. It functions by degrading RNA molecules into smaller nucleotides, effectively removing RNA from the sample.

4. **Additional Context**: While ribonuclease is used for RNA removal, other enzymes like proteases (for proteins) and cellulases (for plant cell walls) may also be involved in the DNA isolation process, but they are not relevant to the removal of RNA.

5. **Final Answer**: The enzyme used for the removal of RNA molecules in the DNA isolation process is **ribonuclease (RNase)**.
