What base pairs are found in DNA and how are they paired?

Answer 1

In DNA, the base pairs consist of four nucleobases: adenine (A), thymine (T), cytosine (C), and guanine (G). The pairing rules for these bases are as follows:

• Adenine (A) pairs with Thymine (T) through two hydrogen bonds.
• Cytosine (C) pairs with Guanine (G) through three hydrogen bonds.

This complementary base pairing is crucial for the structure of the DNA double helix, where A-T and C-G pairs maintain the stability of the DNA molecule.
