Answer:

The basic pairing rule for DNA is: Adenine is paired with Thymine, Guanine is paired with Cytosine and vice versa.

Explanation:

The nitrogenous bases that occur in the DNA molecule are: adenine, guanine, cytosine and thymine.

DNA is characterized by being a very long chain and having a double helix, that is, it has two filaments of polynucleotides interconnected by hydrogen bonds between pairs of specific nitrogenous bases. Adenine binds to thymine, while cytosine binds to guanine and vice versa. This is the basic pairing rule for DNA.
