Mutation Blog

The different types of mutations include substitution, insertion, and deletion. In substitution,a letter is switched with another letter, which may change the stop codon and cause it to endlessly stop producing. Insertion is when an extra letter is inserted into the dna, thus shifts all the frames back one letter.In deletion,one of the nucleotides are deleted making the first letter of the next frame go into the last space of the first frame and changing the whole structure.
