Explanation:
Protons of atoms are the atomic particles with a positive charge while electrons bear a negative charge. Protons are found in the nucleus together with neutrons (that have no charge). They are held together by strong nuclear forces that overcome the repulsive forces between the positive charges in the nucleus. The electrons orbit around the nucleus and are kept in orbit by the electromagnetic attraction of the positive nucleus.
I found this in a website, “A mutation is a change in DNA, the hereditary material of life. ... So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur.”
