What are the four kinds of bases found in DNA?

In DNA, there are four types of nitrogenous bases that play a crucial role in genetic encoding. These bases are:

1. Adenine (A): One of the two purine bases, adenine pairs with thymine in the DNA double helix.

2. Thymine (T): The second of the two pyrimidine bases, thymine pairs with adenine.

3. Cytosine (C): This is another pyrimidine base, cytosine pairs with guanine.

4. Guanine (G): The second purine base, guanine pairs with cytosine.

The sequence of these bases encodes genetic information, and their specific pairing (A with T and C with G) is critical for the structure of the DNA double helix and the accurate replication of genetic material.
