What factors cause mutations and what is the purpose of a mutation? Write your response in complete sentences and answer both parts of the question. square

Mutations are changes in the DNA sequence of an organism's genome. There are several factors that can cause mutations, including exposure to certain chemicals or radiation, errors during DNA replication, and certain viruses. These factors can cause changes in the DNA sequence, which can lead to changes in the structure and function of the proteins that the DNA codes for.<br /><br />The purpose of mutation is to increase genetic diversity within a population. Mutations can introduce new genetic variation, which can be beneficial for the survival and adaptation of a species. For example, a mutation that increases an organism's resistance to a particular disease or environmental stressor can help it survive and reproduce more effectively. Additionally, mutations can also lead to the development of new traits and characteristics, which can be passed on to future generations.
