A gene is a fundamental unit of heredity that carries instructions for the development, functioning, and characteristics of living organisms.
It is composed of DNA and serves as a template for producing proteins or RNA molecules that perform various biological functions.
Genes determine an individual’s traits, such as eye color and susceptibility to diseases, and they are passed from one generation to the next through reproduction.
The field of genetics studies genes and their role in inheritance, evolution, and the functioning of living organisms.
