Our DNA is organised into small sections, called genes. In biology, the word gene has two meanings. In eukaryotes (such as animals, plants, and fungi), genes are contained within the cell nucleus. Most genes code for specific proteins, or segments of proteins, which have differing functions within the body. You inherit one copy from your father and one copy from your mother. Chromosomes containing thousands of genes are passed from parents to offspring and determine an individual's unique traits. Each gene contains the instructions for making a specific product – usually a protein. 5bask mbkiiv zls bnc dnpzln wmg iweb q9wl cqc pxtaw
