Because DNA is double-stranded, the bases on each strand bond together in pairs. A always bonds with T and G always bonds with C.
the combination of two nucleotides on opposite strands of a DNA molecule that pair up due to the complimentary nature of their nucleotide sequences
A pair of nitrogenous bases, one on each strand of a DNA or RNA double helix, which hold the two strands together by virtue of weak, hydrogen bonds between the bases. There are specific rules that determine which bases can pair: adenine pairs with thymine (in DNA) or uracil (in RNA), and guanine pairs with cytosine.
The basic units of DNA and RNA, base pairs are chemical structures made up of the chemicals adenine, thymine, guanine and cytosine, which are designated by the letters A, T, G and C, respectively. Adenine always pairs with thymine and guanine always pairs with cytosine, creating the pairs or nucleotides in which genetic information is found.
A (Adenine) pairs with T (Thymine) and C (Cytosine) pairs with G (Guanine). These base pairs form the ladder of the DNA molecule.

In DNA, there are four possible bases: cytosine (C), guanine (G), adenine (A), and thymine (T). Cytosine and thymine are pyrimidine bases; adenine and guanine are purine bases. Cytosine is complementary to guanine while adenine is complementary to thymine. If one strand of DNA has the sequence ATTGC then the complementary strand will be TAACG. Two complementary bases constitute a base pair. In RNA, thymine is replaced by uracil.
The DNA bases are always held together in pairs by weak hydrogen bonds attaching to one of the strands in the DNA double helix. Adenine always pairs with thymine, and guanine always pairs with cytosine.

The chemical structures that form the units of DNA and RNA and that encode genetic information i.e. the bases that make up the base-pairs are A, G, T, C and U (see DNA). Strictly, a base pair is a pair of complementary bases (i.e. the A:T, G:C and A:U interactions) held together by hydrogen bonds. However, this term is used loosely as a measure of DNA and RNA length (although RNA is single-stranded). The term is also used interchangeably with "nucleotide" although the latter is composed of a five-carbon sugar joined to a phosphate group and one of the bases.
