Answer:
C. frameshift mutation
Explanation:
Frameshift mutation is a type of gene mutation that occurs when one or more nucleotide bases are inserted(added) or deleted (lost) from a DNA strand. This results to a shift or alteration in the reading frame of the codons in the mRNA, hence resulting to wrong placement of amino acids. This kind of mutation alters the amino acid sequence during protein translation.
Frameshift mutations result to deleterious changes amino acid sequence of a protein and can cause diseases like , Crohn's disease and some kinds of cancer.
