Does our blood have proteases and nucleases?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks whether our blood contains two specific types of enzymes: proteases and nucleases.

2. **Definition of Enzymes**: Proteases are enzymes that break down proteins by hydrolyzing the peptide bonds, while nucleases are enzymes that break down nucleic acids by hydrolyzing the phosphodiester bonds.

3. **Presence in Blood**: It is important to note that human blood does not contain proteases or nucleases. This means that these enzymes are not present in the blood itself.
