Name the four bases present in DNA.

Explanation

To answer the question about the four bases present in DNA, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Components of DNA**: DNA (Deoxyribonucleic Acid) is composed of nucleotides, which are the building blocks of DNA. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base.

2. **List the Nitrogenous Bases**: The nitrogenous bases in DNA are classified into two categories: purines and pyrimidines.
- **Purines**: These are larger, double-ring structures. In DNA, the purines are:
