In biology‚ term- mutation has been described as changes to the base pair sequence of the genetic material of an organism. Mutations can be caused by: copying errors in the genetic material during cell division‚ by exposure to ultraviolet or ionizing radiation‚ chemical mutagens‚ or viruses‚ or can occur deliberately under cellular control during processes such as hypermutation. In multicellular organisms‚ mutations can be subdivided into germ line mutations‚ which can be passed on to descendants

9.7 Option – Genetics: The Code Broken? Contextual Outline Science has come a long way since Mendel’s important work on identifying the transmission of inherited factors across generations. The code for transmitting this genetic information has been identified and models have been developed to explain gene functioning. Transcription of the information into functional proteins is now well understood and models are being developed to test how genes direct the structure‚ function and development
