What is the significance of adding proteases at the time of isolation of genetic material (DNA)?

Explanation

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

1. **Understanding the Isolation of DNA**: When isolating DNA from cells, it is essential to separate it from other cellular components, including proteins.

2. **Role of Proteases**: Proteases are enzymes that break down proteins into smaller peptides or amino acids. They are added during the DNA isolation process to degrade cellular proteins.

3. **Source of Proteins**: The proteins that need to be degraded are primarily those present in the cells from which the DNA is being extracted. These proteins can include histones (which are associated with DNA) and other cellular proteins.
