What is a DNA?

Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.

Moreover, deoxyribonucleic acid (DNA) is a molecule that 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.

Therefore, DNA is made up of a chain of molecules called Nucleotides. Each nucleotide contains a nitrogen base, a sugar group and a phosphate group. Four possible nitrogen bases can be present in DNA; Adenine (A), Thymine (T), Guanine (G) and Cytosine (C). Human DNA contains billions of DNA bases.
