Mutations Exercises
You are given the template sequence of an original DNA, and several mutations in the template
(on the next page). Figure out the MRNA sequence and protein sequence of each template, and
then determine the type of mutation that occurred, relative to the original sequence. Choose
from the following mutational types. Classify each mutation at both the DNA and protein level:
A. DNA level
a. Point mutation - transition
b. Point mutation – transversion
c. Frameshift
B. Protein level
a. Synonymous
b. Nonsynonymous – missense
c. Nonsynonymous - nonsense
d. Frameshift
