What is a gene? Is it a section of DNA that encodes a specific protein or is it a large molecule that performs a specific function or is it a point that joins 2/2 of a chromosome or is it a structure that contains many chromosomes?

A gene is a section of DNA that encodes a specific protein. It is the basic physical and functional unit of heredity and carries instructions for creating and controlling various traits and functions within an organism. Each gene is responsible for a specific trait or function, and together they make up the entire genetic makeup of an organism. Genes are located on chromosomes, which are long DNA molecules that contain many genes.
