Abstract

The total DNA of an organism is called the genome. DNA contains all the instructions for how to build an organism and how that organism will function. Some DNA sequences are repeated thousands and thousands of times throughout the genome. Repeats lined up one after another are called satellite DNA. The number of copies of a given satellite DNA sequence can rapidly change, and differ among individuals. Although satellite DNAs were once considered useless, researchers are continuously discovering their important roles in various organisms. Satellite DNAs are essential for keeping organisms functioning properly. They help cells divide and keep the genome integrity. They can affect behavior, health, and help the organism to overcome stressful conditions. In these ways, satellite DNAs increase Earth’s biodiversity.
