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, & 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.

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.

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.

What is the Function of DNA? - sciencenewstoday.org
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 function & structure (with diagram) (article) | 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.

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 are DNA and Genes? - learn.genetics.utah.edu
But you can't tell which one of these organisms it came from just by looking at it. That's because DNA looks exactly the same in every organism on Earth. All living things have DNA. And whether it comes from you, a pea plant, or your pet rat, it's all the same molecule. It's the order of the letters in the code that makes each organism different.
