a)
Insertion Mutation
b)
Translocation
c)
Silent Mutation
d)
Deletion Mutation
8.

a)
Substitution Mutation
b)
Silent Mutation
c)
Frameshift Mutation
d)
Translocation
9.
Are all mutations bad?
a)
Yes
b)
No
10.
Why are insertion and deletion mutations so harmful?
a)
They change all of the codons from the mutation on down the line, which changes the amino acid sequence
b)
They insert things that an organism doesn't need.
c)
They often delete things that organisms need.
d)
Insertion and deletions are not any more harmful than substitution mutations.
11.
Why is the order of amino acids so important?
a)
The order of amino acids dictates what shape the protein will fold into.
b)
It is not important. The protein folding chamber will force the protein to fold into the correct shape.
