DNA Base Pairing: Does A Always Pair with T and C with G?
“With dna does a always pair with t and c always pairs with g”
Summary
In double‑stranded DNA, adenine (A) always pairs with thymine (T) and cytosine (C) always pairs with guanine (G) through complementary hydrogen bonding. This rule holds universally for DNA molecules.

- Base Pair
The two strands are held together by hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine. One copy of the human genome consists of approximately 3 billion base pairs of DNA, which are distributed ...
- Adenine
Adenine (A) is one of the four nucleotide bases in DNA, with the other three being cytosine (C), guanine (G) and thymine (T). Within a double-stranded DNA molecule, adenine bases on one strand pair with thymine bases on the opposite strand.

Complementary pairing of two ... strands of DNA and RNA. In the double helix structure of the DNA molecule, adenine (A) forms a base pair with thymine (T), and guanine (G) with cytosine (C)....
- Base pairs - Genomics Education Programme
A unit of two bases in a molecule of DNA or RNA. In DNA, adenine always pairs with thymine (A-T), and guanine always pairs with cytosine (G-C). RNA is the same, except that adenine always pairs with uracil (A-U).
- DNA Structure | DNA and DNA Extraction - passel
There are only 4 nucleotides in DNA, Adenine (A), Guanine (G), Thymine (T), and Cystosine (C). The chemical structures of Thymine and Cytosine are smaller, while those of Adenine and Guanine are larger. Size and structure of the specific nucleotides cause Adenine and Thymine to always pair together while Cytosine and Guanine always pair together.

The nucleotides are identical except for the base, which can be an adenine, thymine, guanine or cytosine. There are chemical cross-links between the two strands in DNA, formed by pairs of bases held together by hydrogen bonds.
- 5.4: Base Pairing in DNA and RNA - Biology LibreTexts
The rules of base pairing explain the phenomenon that whatever the amount of adenine (A) in the DNA of an organism, the amount of thymine (T) is the same (called Chargaff's rule). Similarly, whatever the amount of guanine (G), the amount of cytosine (C) is the same.
