What is DNA? - Genetics Home Reference - NIH
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).
DNA (Deoxyribonucleic Acid) | Talking Glossary of Genetic ...
DNA, or deoxyribonucleic acid, is the central information storage system of most animals and plants, and even some viruses. The name comes from its structure, which is a sugar and phosphate backbone which have bases sticking out from it--so-called bases.

deoxyribonucleic acid (DNA), Flashcards | Quizlet
deoxyribonucleic acid (DNA), 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 is found inside a special area of the cell called the. nucleus.
DNA - Deoxyribonucleic Acid - Definition and Function ...
Deoxyribonucleic Acid Definition. DNA – the abbreviation for deoxyribonucleic acid. DNA is the molecule of heredity; its sequences form the body’s genetic code.Each cell in the body contains DNA within the chromosomes in its nucleus (except erythrocytes, which do not have nuclei).
Definition of deoxyribonucleic acid | Dictionary.com
deoxyribonucleic acid; a nucleic acid that is the main constituent of the chromosomes of all organisms (except some viruses). The DNA molecule consists of two polynucleotide chains in the form of a double helix, containing phosphate and the sugar deoxyribose and linked by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine.
DNA (Deoxyribonucleic acid) - GIANT Microbes
FACTS: Deoxyribonucleic acid, or DNA, is the amazing molecular double helix that contains the genetic codes for all known life. First identified in 1869 and accurately described in 1953, its very existence provides a new understanding about how life works.
DNA - Wikipedia
Deoxyribonucleic acid (/ d i ˈ ɒ k s ɪ r aɪ b oʊ nj uː k l iː ɪ k, -k l eɪ-/ ; DNA) is a molecule composed of two chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses.
