A person’s DNA, short for deoxyribonucleic acid, is a molecule that functions as a storehouse of genetic information. The discovery of DNA was a major breakthrough in medical science. While Watson and Crick gave the actual structure of the molecule, the credit of its discovery and identification goes to Friedrich Miescher.

Chromosomes are considered the basic structures of heredity. They carry the codes that give rise to the expression of the characteristic features of an organism. Humans have 46 chromosomes. In 1997, a team of scientists J.J. Harrington, G.V. Bokkelen, R.W. Mays, K. Gustashaw, and H.F. Willard synthesized artificial chromosomes. These chromosomes are stable up to six weeks. These chromosomes can be used as vectors to carry genes of interest into other cells and for the study of their expression.
