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 (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.

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.

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]

DEOXYRIBONUCLEIC ACID Definition & Meaning | Dictionary.com
In living things, deoxyribonucleic acid, more commonly known as DNA, carries biological information that instructs the cells of organisms on how to form, grow, and reproduce.

What Is Deoxyribonucleic Acid and How Does It Work?
Deoxyribonucleic acid, more commonly known as DNA, carries the genetic instructions for the development, functioning, and reproduction of all known organisms and many viruses. Present in nearly every cell, it contains the specific genetic code that makes each organism unique.

Nucleic acid - DNA, Genes, Molecules | Britannica
DNA is a polymer of the four nucleotides A, C, G, and T, which are joined through a backbone of alternating phosphate and deoxyribose sugar residues. These nitrogen-containing bases occur in complementary pairs as determined by their ability to form hydrogen bonds between them.

Definition of deoxyribonucleic acid - NCI Dictionary of Genetics Terms
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.
