Verified step by step guidance1
Understand that DNA is composed of two strands forming a double helix, where the bases on one strand pair with the bases on the other strand.
Recall that the base pairing rules in DNA are determined by hydrogen bonding between specific nitrogenous bases.
Identify the four nitrogenous bases in DNA: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
Recognize that Adenine (A) pairs with Thymine (T) through two hydrogen bonds, while Cytosine (C) pairs with Guanine (G) through three hydrogen bonds.
Note that these specific pairings (A-T and C-G) are crucial for the stability of the DNA double helix and for accurate DNA replication.
