Nucleotides are acidic in nature.

Explanation

### Step-by-Step Solution:

1. **Understanding Nucleotides**:
- Nucleotides are the basic building blocks of nucleic acids, which include DNA and RNA. They are composed of three main components: a sugar molecule, a nitrogenous base, and a phosphate group.

2. **Components of Nucleotides**:
- **Sugar**: The sugar in nucleotides can either be ribose (in RNA) or deoxyribose (in DNA).
- **Nitrogenous Base**: This can be a purine (adenine or guanine) or a pyrimidine (cytosine, thymine in DNA, or uracil in RNA).
