What is deoxy ribonucleic acid? explain briefly

Deoxyribonucleic acid, or DNA, is the molecule that holds the genetic material for all organisms. It is found in most viruses, all bacteria and all plant and animal cells. DNA is found within the nucleus, or control center, of the cell. It can also be found within mitochondria and in chloroplasts, in those cells that have them, such as plants.

A deoxyribonucleic acid molecule is made up of a long chain of nucleotides.


Deoxyribonucleic acid (DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. DNA is a nucleic acid; alongside proteins and carbohydrates, nucleic acids compose the three major macromolecules essential for all known forms of life. Most DNA molecules consist of two biopolymer strands coiled around each other to form a double helix. The two DNA strands are known as polynucleotides since they are composed of simpler units called nucleotides. Each nucleotide is composed of a nitrogen-containing nucleobase—either guanine (G), adenine (A), thymine (T), or cytosine (C)—as well as a monosaccharide sugar called deoxyribose and a phosphate group.

The answer lies in a molecule called deoxyribonucleic acid (DNA), which 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.It is made up of a long chain of nucleotides.
