On the left: nucleotides that forms the DNA and their complementary. Between A and T there are 2 hydrogen bounds, while 3 are between C and G. On the right a DNA sequence and its complementary strand.
In genetics, a double-stranded DNA strand consists of two complementary strands of base pairs, which are non-covalently connected via two or three hydrogen bonds.

A nucleotide is a chemical compound that consists of a heterocyclic base, a sugar, and one or more phosphate groups. ... The structure of part of a DNA double helix. ...

Covalent bonding is a description of chemical bonding that is characterized by the sharing of pairs of electrons between atoms. ... Snapshot from a simulation of liquid water. ...
Since there is only one complementary base for any of the bases found in DNA and in RNA, one can reconstruct a complementary strand for any single strand. This is essential for DNA replication. This article or section is in need of attention from an expert on the subject. ...
For example, the complementary strand of the DNA sequence
Compliment and complementation have several different meanings in Biology, see Complement for other uses. Biology studies the variety of life (clockwise from top-left) E. coli, tree fern, gazelle, Goliath beetle Biology (from Greek Βìο meaning life and Λoγος meaning the study of) is the study of life. ...

Molecularbiology's classical period began in 1953, with James Watson and Francis Crick's discovery of the double helical structure of DNA (Watson and Crick 1953a, 1953b).
Another usage of “moleculargenetics” is to refer to any study of genetics at the molecular level, that is any study of the molecularbiology of the gene, such as in the new genomic studies.

DNA has two types of digital information--the genes that encode proteins, which are the molecular machines of life, and the gene regulatory networks that specify the behaviour of the genes.
Moleculargenetic research has identified specific allele variants of candidate genes corresponding to these neurotransmitter systems to be associated with PG.
Insights into tumor angiogenesis biology have led to the identification of a number of molecules, which are important for the progression of these processes.
