Document Summary
Are effected by uv lights, can"t be exposed to light or get skin cancel: won"t go to progeny, but it will pass on to your own cells, through cell replication, are not sex linked. Spontaneous and induced: normal products of metabolism (metabolic damage) are the ones that cause bulk of mutation in the cell. Some mutants are good to eat: delicious apples resulted from propagation of the tissue of an apple that was originally somatic mosaic. If they happen at specific times the base pairs will pair with the wrong base pair doubles) it might accidently slip back or jump ahead and change the reading. Expansion of trinucleotide repeats: polymerase when copying multiple identical codes (ie. cag"s or other everything that"s in front of it. Ionizing radiation penetrate human tissue and smash and break. Deaminating agents: when reacts with dna bases and change it pairing witg the wrong base pairs, since its been deaminated to look different.
