The complementary bases in DNA are attracted to each other by hydrogen bonds. Here are the steps explaining this process:

1. DNA is made up of two strands, each containing a sequence of nucleotides. Each nucleotide contains a sugar, a phosphate group, and a nitrogenous base.

2. The nitrogenous bases are adenine (A), thymine (T), guanine (G), and cytosine (C). In DNA, adenine always pairs with thymine, and guanine always pairs with cytosine. These are known as base pairs.

3. The attraction between these base pairs is due to hydrogen bonds. Adenine and thymine form two hydrogen bonds, while guanine and cytosine form three hydrogen bonds.

4. These hydrogen bonds hold the two strands of DNA together, but they are weak enough to be broken so that the DNA can be replicated or transcribed.

5. Therefore, the complementary bases in DNA are attracted to each other by hydrogen bonds.
