What is the meaning of DNA?

DNA is the acronym for Deoxyribonucleic acid. DNA is the carrier of genetic information in living organisms. DNA has the ability to self-replicate. DNA has four different nucleotide groups, which are made from sugar known as deoxyribose, a phosphate group, and one of four nucleobases (Adenine, guanine, cytosine, and thymine). DNA is made of two strands that coil around each other to form the double-helical structure.

The two strands are tightly held together by hydrogen bonds. DNA is tightly packed with histones to form a nucleosome. DNA is also arranged into structures known as chromosomes DNA was first identified by Friedrich Miescher in 1869. In 1953, Francis Crick and James Watson identified the molecular structure (double helix) of DNA.
