DNA - Wikipedia
DNA and ribonucleic acid (RNA) are nucleic acids. Alongside proteins, lipids and complex carbohydrates (polysaccharides), nucleic acids are one of the four major types of macromolecules that are essential for all known forms of life.

DNA | Definition, Discovery, Function, Bases, Facts ...
DNA is an organic chemical of complex molecular structure found in all prokaryotic and eukaryotic cells. It codes genetic information for the transmission of inherited traits. The structure of DNA was described in 1953, leading to further understanding of DNA replication and hereditary control of cellular activities.

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.

Deoxyribonucleic Acid (DNA) Fact Sheet
Deoxyribonucleic acid (DNA) is a molecule that contains the biological instructions that make each species unique.

The Structure of DNA and RNA – Introductory Biology
There are two types of nucleic acids: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Each of these molecules has a unique structure that enables it to fulfill specific functions within the cell. Understanding the structure of DNA and RNA is key to grasping how genetic information is encoded, replicated, and expressed within an organism.

What is DNA?: MedlinePlus Genetics
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? Understanding the Blueprint of Life
DNA is the molecule that carries hereditary information from one generation to the next. This means that offspring inherit a combination of genes from their parents, and this genetic inheritance determines many aspects of their traits.
