Mutations are changes in the genetic material (DNA or RNA) of a cell. These changes can cause a variety of effects, from mild to serious, depending on the type and location of the mutation and the organism in which it occurs. Mutations can result in changes in the organism’s physical characteristics, the production of new proteins, or the introduction of new genetic material into the organism’s genome. Mutations can be caused by environmental factors, such as radiation, or they can occur spontaneously.
