How do histones acquire positive charge?

Explanation

**Step-by-Step Solution:**

1. **Understanding Histones**: Histones are proteins found in the nuclei of eukaryotic cells. They play a crucial role in the packaging of DNA into structural units known as nucleosomes.

2. **Nature of Histones**: Histones are classified as alkaline proteins, which means they are basic in nature. This basicity is important for their function in DNA packaging.

3. **Amino Acids in Histones**: The positive charge of histones is primarily due to the presence of basic amino acids, specifically arginine and lysine. These amino acids have side chains that can accept protons (H+ ions), which gives them a positive charge.
