Mutation - Wikipedia, the free encyclopedia
In biology, a mutation is a randomly derived change to the nucleotide sequence of the genetic material of an organism. Mutations can be caused by copying errors in the genetic material during cell d...

With a missense mutation, the new nucleotide alters the codon so as to produce an altered amino acid in the protein product. ... With a nonsense mutation, the new nucleotide changes a codon that specified an amino acid to one of the STOP codons (TAA, TAG, or TGA). Therefore, translation of the messenger RNA transcribed...
