Types of mutaions

Insertions-

Insertions are where a new base is inserted into the DNA base sequence where it shouldn't be.

An insertion changes the way that the groups of 3 bases are 'read' which can then change the amino acids that they are coding for. 

Insertions can change more than one amino acid due to knock on effects on bases further on in the sequence. e.g...

Original gene----->  T    A    T /   A …
