HELP! (Will give brainliest answer!)

Suppose you are a doctor treating a patient with a point mutation in a protein-encoding gene.

The mutation is as follows:
Correct Gene: TACAAGCCTTATACT
Mutated Gene: TACAAGGCCTTATACT

Please answer the following questions…

A. What is the name of this type of mutation?
B. Is this a frameshift mutation? Why or why not?
C. What would be the polypeptide produced by the correct gene, and the polypeptide produced by the faulty gene?
D. Suppose this gene coded for a protein involved in assembly of the RNA polymerase enzyme. What symptoms would you expect your patient would exhibit?
E. Suppose this was a trait experienced in a specific family history. What type of diagram could you use to determine the presence of this trait throughout the family tree?
