Within each chromosome are specific sections of DNA called genes. Each gene contains the code or recipe to make a specific protein. These proteins determine how we grow and what traits we inherit from our parents.The gene is sometimes called a unit of heredity.ithin each chromosome are specific sections of DNA called genes.
