BioProcess International™ Glossary
deoxyribonucleic acid, a biopolymer found primarily in the nucleus of cells. It carries genetic information for making all the structures and materials necessary for life. Its double-stranded helical molecular chain is held together by weak bonds between base pairs of nucleotides (cytosine, guanine, adenine, or thymine) linked with ribose sugar molecules.

Dna Definition from Encyclopedia Dictionaries & Glossaries
Wikipedia English - The Free Encyclopedia
Deoxyribonucleic acid (DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. DNA is a nucleic acid; alongside proteins and carbohydrates, nucleic acids compose the three major macromolecules essential for all known forms of life. Most DNA molecules are double-stranded helices, consisting of two long biopolymers made of simpler units called nucleotides—each nucleotide is composed of a nucleobase (guanine, adenine, thymine, and cytosine), recorded using the letters G, A, T, and C, as well as a backbone made of alternating sugars (deoxyribose) and phosphate groups (related to phosphoric acid), with the nucleobases (G, A, T, C) attached to the sugars.

President's DNA Initiative Glossary
Often referred to as the "blueprint of life," DNA is the genetic material present in the nucleus of cells which is inherited half from each biological parent. DNA is a chemical substance contained in cells, which determines each person's individual characteristics. An individual's DNA is unique except in cases of identical twins.

Terms and Definitions
The substance of heredity; a large molecule that carries the genetic information that cells need to replicate and to produce proteins. DNA is a double-stranded molecule held together by weak 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.
Deoxyribonucleic acid. The very large molecules in the nucleus of all living cells. It carries the genetic code.

Dictionary of Medicine (Shahram)
The molecule that encodes the genetic information. DNA is a double-stranded molecule that is held together by weak bonds between base pairs of nucleotides to form a double helix. The four nucleotides in DNA contain the bases: adenine (A), guanine (G), cytosine ©, and thymine(T). Base pairs form naturally only between A and T and between G and C so the base sequence of each single strand of DNA can be simply deduced from that of its partner strand. The code is in triplets such as ATG. The base sequence of that triplet in the partner strand is therefore TAC.
