DNA Sequencing

This is a Graph of the DNA Sequencing.

For Abby she had 1 base change. It was GAG -> GTG. She was a 97% Similarity to others. Which = Point Mutation. Protein = GLU-> VAL Disease?

BOB  THE->STOP= Truncation Mutation

Carol ACC  CTG  AGG = Frame Shift Mutation

1) Each of the other three people does not match the normal control. I say this because something happened in the DNA
2) NO All the protein matches the normal control. I say this because of the change in the DNA of the person
3) For each person I would expect a normal state just because of the protein matches. There is only really one that does not match. Sometimes one can make difference and sometimes it don't.
