DNA - Wikipedia
Deoxyribonucleic acid (pronunciation ⓘ; [1] DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses.

DEOXYRIBONUCLEIC ACID Definition & Meaning - Merriam-Webster
Michael Schulman, New Yorker, 16 Mar. 2026 Watson shared a 1962 Nobel Prize with Francis Crick and Maurice Wilkins for discovering that deoxyribonucleic acid, or DNA, is a double helix, consisting of two strands that coil around each other to create what resembles a long, gently twisting ladder.

DNA | Definition, Discovery, Function, Bases, Facts, & Structure ...
DNA, organic chemical of complex molecular structure that is found in all prokaryotic and eukaryotic cells and in many viruses. DNA codes genetic information for the transmission of inherited traits.

Deoxyribonucleic Acid (DNA) - National Human Genome Research Institute
Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix.

Deoxyribonucleic Acid (DNA) Fact Sheet
Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction.

Deoxyribonucleic acid (DNA) - Microbiology Notes
Deoxyribonucleic acid (DNA) is a polymer of deoxyribonucleotides linked together by phosphodiester bonds. It contains the bases adenine, guanine, cytosine, and thymine.

What is DNA? Definition, Function & Structure - Cleveland Clinic
DNA (deoxyribonucleic acid) is a set of instructions for creating the proteins that make your body work. Two strands of DNA together form a double helix — a bit like a spiral staircase.

Definition of deoxyribonucleic acid - NCI Dictionary of Genetics Terms
Genes are short pieces of DNA that carry specific genetic information. The molecule inside cells that contains the genetic information responsible for the development and function of an organism. DNA molecules allow this information to be passed from one generation to the next.

Deoxyribonucleotide - Wikipedia
They are the monomeric units of the informational biopolymer, deoxyribonucleic acid (DNA). Each deoxyribonucleotide comprises three parts: a deoxyribose sugar (monosaccharide), a nitrogenous base, and one phosphoryl group. [1]

DNA: Properties, Structure, Composition, Types, Functions
Deoxyribonucleic acid (DNA) is the heredity material found in humans and all living organisms. It is a double-stranded molecule and has a unique twisted helical structure.
