Deoxyribonucleic Acid (DNA)
- Deoxyribonucleic acid (DNA) is an organic molecule with a complex molecular structure.
- DNA molecule’s strands are made up of a long chain of monomer nucleotides. It is arranged in a double helix structure.
- James Watson and Francis Crick discovered that DNA is a double-helix polymer in 1953.
- It is essential for the transfer of the genetic characteristic of the living being from one generation to the other generation.
- The majority of DNA is found in the cell nucleus so it is called nuclear DNA.
- DNA stores data in the form of a code made up of four Nitrogenous bases.
- Purines:
- Adenine (A)
- Guanine (G)
- Pyrimidines
- Cytosine (C)
- Thymine (T)
