Which of the following mutations would cause the most dramatic change in the polypeptide product of a certain gene?

Answer 1

The type of mutation that would cause the most dramatic change in the polypeptide or protein product of a certain gene is the base-pair deletion.  A deletion is a mutation in which the part or the base is lost during the process of replication. Any number of nucleotides can be deleted from a single base to an entire piece of chromosome.
