What genetic mutations produce the greatest risk of skin cancer? Cancer begins when one or more genes in a cell mutate. This either creates an abnormal protein or no protein at all‚ which causes mutated cells to multiply uncontrollably. The Most common gene to carry skin cancer would be the MC1R (melanocortin-1 receptor). Increasing evidence is showing that the greater number of variations in this gene‚ the greater the risk for melanoma. It also carries a more moderate risk that the CDKN2A mutation

The uppermost strand in this structure is called the coding strand. The second strand that lies below the coding strand is called the template strand. In order for a RNA polymerase to go from the upper strand to the second strand it must go through the process called transcription. First‚ the RNA polymerase must attach on to one of the genes on the coding strand on DNA. Once the RNA polymerase attaches‚ it must then begin the process called initiation. This means that the RNA polymerase opens up
