A gene is the basic physical and functional unit of heredity. Genes, which are made up of DNA, act as instructions to make molecules called proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. The Human Genome Project has estimated that humans have between 20,000 and 25,000 genes. Every person has two copies of each gene, one inherited from each parent. Most genes are the same in all people, but a small number of genes (less than 1 percent of the total) are slightly different between people.
DNA can be thought of as a code, containing all the instructions that tell a cell what to do. It is made up of genes. Humans have around 25,000 genes in total. You inherit half your DNA from your mother and half from your father, so you have two copies of every gene.Your genes carry all the information that makes you, you. They tell your body to have blonde hair, or brown skin, or green eyes for example.nside the nucleus are 23 pairs of chromosomes. These are long strings of DNA. DNA stands for deoxyribonucleic acid (pronounced dee-oxy-rye-bow-nu-clay-ik acid). Each string of DNA is shaped like a twisted ladder, which is called a double helix.
