Which base pairs with adenine in DNA?

Adenine is one of the four nucleotide bases in DNA and pairs specifically with thymine through hydrogen bonds. This base pairing is fundamental to the structure of the DNA double helix, where adenine-thymine pairs form complementary relationships, stabilizing the overall DNA structure. The pairing occurs due to the specific number of hydrogen bonds formed: adenine creates two hydrogen bonds with thymine, which is essential for the replication and transcription processes in genetics.

Knowing this, the other bases—cytosine and guanine—pair with each other instead, and uracil is found in RNA, not DNA. Thus, thymine is the correct base that pairs with adenine in the context of DNA.
