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 - Wikipedia
Deoxyribonucleic acid (/ diːˈɒksɪˌraɪboʊnjuːˌkliːɪk, - ˌkleɪ -/ ⓘ; [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
Jeff Spry, Space.com, 27 Feb. 2025 Folate is needed to make DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) and helps produce healthy red blood cells. Lainey Younkin, Ms, Rd, Verywell Health, 22 Mar. 2024. Human genomes, the massive set of genetic material every person carries, are made up of , or DNA.

DNA | Definition, Discovery, Function, Bases, Facts, & Structure ...
Deoxyribonucleic acid (DNA) is an organic chemical that contains genetic information and instructions for protein synthesis. It is found in most of every organism. DNA is a key part of reproduction in which genetic heredity occurs through the passing down of DNA from parent or parents to offspring.

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.

What is DNA?: MedlinePlus Genetics
DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

DEOXYRIBONUCLEIC ACID Definition & Meaning | Dictionary.com
Deoxyribonucleic acid —better known by the abbreviation DNA —is a large, complex molecule that allows cells to function and carries the genetic code that determines the traits of a living organism.

Deoxyribonucleic Acid - The Definitive Guide | Biology Dictionary
Deoxyribonucleic acid, DNA, or desoxyribonucleic acid is a molecule with a double helix structure that carries the sequences of genetic code – the basis of all life. Packaged tightly into chromosomes, DNA can be copied and translated to manufacture specific proteins.

Nucleic acid - DNA, Genes, Molecules | Britannica
Deoxyribose sugar molecules and phosphate molecules form the outer edges of the DNA double helix, and base pairs bind the two strands to one another. 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.

DNA - Definition, Function, Structure and Discovery | Biology Dictionary
Deoxyribonucleic acid, or DNA, is a biological macromolecule that carries hereditary information in many organisms. DNA is necessary for the production of proteins, the regulation, metabolism, and reproduction of the cell.
