· A gene is the basic physical and functional unit of heredity. Genes, which are made up of DNA, act as instructions to make molecules called proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.

Term gene was coined by Johansen (1900). A hereditary determiner specifying a biological function: a unit of inheritance (DNA) located in a fixed place on the chromosome is called gene. Mendel considered every character as unit which is controlled by a factor presently called gene. Chemically gene is a segment of DNA which controls one character and physically is a part of chromosome.
