Answer:
Hi, there the answer is
C.It is a frameshift mutation that changes many amino acids.
Step-by-step explanation:
Due to the triplet nature of gene expression by codons, the insertion of the single Adenine nucleotide will disrupt the reading frame of the gene (frameshift mutation), such that it is no longer evenly divisible by three.
Thus, resulting in a completely different translated protein from the original.
Hope this helps :)
