DNA-ase and RNA-ase are enzymes produced by

Options

A. Salivary glands
B. Pancreas
C. Stomach
D. Intestine.

Answer

**Step-by-Step Solution:**

1. **Identify the Enzymes**: The question asks about DNA-ase and RNA-ase, which are enzymes that break down nucleic acids. DNA-ase specifically breaks down DNA, while RNA-ase breaks down RNA.

2. **Understand the Source of the Enzymes**: Both DNA-ase and RNA-ase are classified as nucleases. Nucleases are enzymes that hydrolyze the phosphodiester bonds between nucleotides in nucleic acids.

3. **Determine the Organ Producing These Enzymes**: The pancreas is known for producing a variety of digestive enzymes, including nucleases. Pancreatic juice contains DNA-ase and RNA-ase, which are secreted into the small intestine to aid in digestion.

4. **Evaluate Other Options**:
- **Salivary Glands**: These primarily secrete saliva, which contains enzymes like salivary amylase and salivary lipase, but not DNA-ase or RNA-ase.
- **Stomach**: The stomach secretes pepsin and hydrochloric acid, but does not produce nucleases.
- **Intestine**: While the intestine does have enzymes, they are mainly from the pancreas and liver, and do not include DNA-ase or RNA-ase as secreted by the intestine itself.

5. **Conclusion**: Based on the information, the correct answer is that DNA-ase and RNA-ase are enzymes produced by the **pancreas**.

**Final Answer**: DNA-ase and RNA-ase are enzymes produced by the **pancreas**.
