Many mutations are meaningless and inneffective as there are up to four triplet codes that each code for the same amino acid, and so if one base is changed, the overall result is unchanged, and the protein will be as if the mutation never happened. However, if multiple mutations occur on the same DNA or RNA strand, this can result in improperly built RNA which translates into improperly formed proteins and even malformed body structures and uncontrolled cell growth (cancer). See Protein Synthesis for more information on this.
