Final answer:
DNA and RNA share base pairs but differ in the pairing of adenine with either thymine or uracil. Complementary base pairings are fundamental for DNA replication and transcription.
Explanation:
Base pairs: In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). In RNA, adenine (A) pairs with uracil (U) instead of thymine. These complementary base pairings play a crucial role in DNA replication and transcription.
Example: In DNA, the base pair AT (adenine-thymine) and CG (cytosine-guanine) are complementary base pairs.
Hydrogen Bonds: The bonding between these base pairs is through hydrogen bonds, forming the structure of the DNA double helix and RNA.
