DNA Mutation






Hey so I will be talking about DNA mutation(no not the mutts in hunger games). But mutation is caused when a cell copies its DNA in preparation for cell division or DNA is damaged from things like ultraviolet light, nuclear radiation or some chemicals.




WARNING: You will not become a superhero like hulk or spiderman if you jump in toxic waste or or expose yourself to radiation.  





















There are several types of mutation there is frame shift, inversion, and deletion.

Frame shift is when at least one base is added or deleted. Inversion is when the nucleotide sequence reverses. Deletion is when a certain nucleotide is deleted and it messes up the coding.
