teach.genetics.utah.eduHuman cells contain forty-six DNA molecules that when tightly packaged during cell division can be visualized as forty-six chromosomes. The sequence information in each DNA molecule is divided into segments called genes. Each gene contains a blueprint for constructing a unique protein that has a specialized function in the cell.

medlineplus.govA gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases. An international research effort called the Human

pages.mtu.edu⎯ DNA has four bases A, G, T and C. A combined with T and G combined with C ⎯ bp is also used as length unit of chromosome or DNA sequence ⎯ DNA sequence has direction. There are two sides (ends) called 5’ side and 3’ side. ⎯ The homologous chromosomes (chromosome 1, for example) have exactly same length for every individual. AGT CG A
