DNA: Mutations

  • Page ID
    3973
  • This page takes a very brief look at what happens if the code in DNA becomes changed in some way, and the effect that would have on the proteins it codes for. Copying errors when DNA replicates or is transcribed into RNA can cause changes in the sequence of bases which makes up the genetic code. Radiation and some chemicals can also cause changes. The examples which follow show some of the easier-to-understand effects of this.
