What are the four base pairs in DNA?

DNA is a macromolecular polymer composed of deoxynucleotides. Deoxynucleotide consists of base, deoxyribose and phosphoric acid. There are four kinds of bases: adenine (a), guanine (g), thymine (t) and cytosine (c).

Deoxyribonucleic acid (DNA) is a kind of nucleic acid that carries the genetic information necessary for the synthesis of RNA and protein by biological cells, and it is also a biomacromolecule necessary for the development and normal operation of organisms.

A base pair is a pair of matched bases connected by hydrogen bonds (i.e. A-T, G-C, A-U interaction). However, it is usually used to measure the length of DNA and RNA (although RNA is single stranded).

It can also be used interchangeably with nucleotide, although the latter consists of pentasaccharide, phosphoric acid and one base.

Extended data:

Base pairs are chemical structures that form DNA and RNA monomers and encode genetic information. The bases that make up a base pair include A, G, T, C and U. Strictly speaking, a base pair is a pair of matched bases (that is, A: T, G: C, A: U interaction) connected by hydrogen bonds.

However, it is usually used to measure the length of DNA and RNA (although RNA is single stranded). It can also be used interchangeably with nucleotide, although the latter consists of pentasaccharide, phosphoric acid and one base.
