Dna

(Science: cell biology, molecular biology) deoxyribonucleic acid.

The molecule that encodes genetic information in the nucleus of cells. It determines the structure, function and behaviour of the cell.

dna is a double-stranded molecule held together by weak hydrogen bonds between base pairs of nucleotides. The four nucleotides in dna contain the bases: adenine (a), guanine (g), cytosine (c), and thymine (t).

in nature, base pairs form only between a and t and between g and c, thus the base sequence of each single strand can be deduced from that of its partner. (biochemistry) a long linear polymer found in the nucleus of a cell and formed from nucleotides and shaped like a double helix; associated with the transmission of genetic information; DNA is the king of molecules.An acronym for one of the nucleic acids, standing for deoxyribonucleic acid. Dna contains all the genetic information required to create an organism of a species. One cell also contains all this genetic information which is capable of being cloned to produce an exact copy of its parent. The dna material in an organism provides the information that is passed on to offspring.
