DNA | Definition, Discovery, Function, Bases, Facts, & Structure ...
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.

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.

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.

What is DNA?: MedlinePlus Genetics
What is DNA? 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.

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? 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.

DNA: Function, structure, and impact on health - Medical News Today
DNA is a molecule found in most cells that holds each person’s unique genetic code. It is responsible for coding proteins, which are essential to cell growth and development.

DNA structure and function - Khan Academy
In order to understand the biological function of DNA, you first need to understand its molecular structure. This requires learning the vocabulary for talking about the building blocks of DNA, and how these building blocks are assembled to make DNA molecules.

Definition of DNA - NCI Dictionary of Genetics Terms - NCI
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.
