Thanks!

@mazefordays090 Not quite right, it's a substitution mutation as a nucleobase in the sequence is being replaced. 
A frameshift mutation happens when a nucleobase is inserted or deleted which will cause an error in the codon reading.

Ahh… thanks. I was just rereading the textbook and substitution is what I came up with.
