Gene Mutation

Gene duplication is the copying of a region of DNA that contains a gene. This is different from a regulatory mutation, which is a loss of an enhancer portion of a gene. This changes the way the gene is regulated, affecting the development of the part of the organism that it corresponds to without losing this part of the organism. Finally, a coding sequence mutation is a mutation that causes a change in the coding sequence. The coding sequence encodes for the gene product. These mutations include frameshift mutations, missense mutations, nonsense mutations, and silent mutations.
