radiation can alter dna in two different wayslonizing radiation: such as X- ray and gamma radiation energize electrons, causing them to leave atoms and molecules, forming hightly reactive ions. this can cause DNA molecules to break down and triggernoionizing radiation: such as ultriavioles ligh causes the braeking of bonds between purines and pyramindines when two pyrimidine molecules of the same type(T or C) are adjacent to one another on a nucleoside. these pyrimidine dimers distort the sugar phosphate blackbone and prevent proper replication and transcription
