It can also be defined by the following ways-
The functional unit of chromosome situated in a particular locus in which recombination may occur and can take part in mutation is called Gene. Therefore, any single base-pair of DNA is called Gene.
Functions of gene:
- Gene creates the correct replica in order to transfer the hereditary characteristics from one generation to another
- The mutation that occurs in gene is the main element of evolution
- It acts as the unit of physiological activities, such as protein synthesis.
