- DNA - Wikipedia
DNA is a long polymer made from repeating units called nucleotides [6] [7] The structure of DNA is dynamic along its length, being capable of coiling into tight loops and other shapes [8] In all species it is composed of two helical chains, bound to each other by hydrogen bonds

Deoxyribonucleic acid (DNA) is an organic chemical that contains genetic information and instructions for protein synthesis It is found in most cells 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 What is DNA made of?
- What is DNA? - MedlinePlus
DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone DNA is the hereditary material in humans and almost all other organisms Genes are made up of DNA
- What Is DNA? - Verywell Health
Deoxyribonucleic acid (DNA) is the material in cells that carries all genetic information in humans, animals, plants, and all living cells It’s passed down from parents to their offspring, and it’s also self-replicating, which plays a significant role in cell division and organism growth
- What Does DNA Stand For? Definition, Function Structure
All living things have DNA in their cells (and some viruses carry it with them, too) You inherit your DNA from your biological parents — you get half from your mother and half from your father The letters in DNA stand for deoxyribonucleic acid (“dee-OCK-see-rai-bow-new-CLAY-ick A-sud”) A nucleic acid is an acidic substance found in the

Inside every living cell, nestled within the microscopic confines of the nucleus, lies a molecule so powerful and so fundamental that it shapes everything about us — from our eye color to our susceptibility to certain diseases This molecule is DNA: Deoxyribonucleic Acid
- DNA Anatomy: Structure and Cellular Organization
DNA’s building blocks are nucleotides Each nucleotide has three parts: a five-carbon sugar (deoxyribose), a phosphate group, and a nitrogen-containing base The phosphate group attaches to the sugar, forming the backbone of a DNA strand Four types of nitrogenous bases exist in DNA: adenine (A), guanine (G), cytosine (C), and thymine (T)
