A gene is a unit of heredity. It is a segment of DNA that codes for a specific protein. Proteins are the building blocks of life, and they control everything from how your body looks to how it works.
Genes are located on chromosomes. Chromosomes are thread-like structures in the nucleus of cells. Humans have 23 pairs of chromosomes, for a total of 46 chromosomes.
Genes are passed down from parents to their children. This is how traits like eye colour, hair colour, and height are inherited.
Genes are the basic units of heredity.
Noun: gene.
