Acquired (or somatic) mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.
Males are more effected by conditions linked the the X-chromosome. Females have an extra X-chromosome, so if the mutation happens they have a backup. Males are easier targets.<em><u> (PLEASE DON"T COPY WORD FOR WORD)</u></em>
