Would a 3 Nucleotide Insertion Result in a Frameshift?

C is correct. Insertion or deletion of three (or multiples of 3) nucleotides does not result in a frameshift mutation. It only results in the presence (or absence) of some amino acids in the polypeptide.

Would a 3 nucleotide insertion result in a frameshift Why or why not?

Explanation: Frameshift mutations are insertions or deletions of nucleotides in DNA that change the reading frame (the grouping of codons). ... Since codons are read in groups of 3, an insertion of 3 or 6 would not cause a shift in the positions of all subsequent nucleotides.

Will an insertion or a deletion of three nucleotides result in a frameshift mutation?

Frameshift mutations arise when the normal sequence of codons is disrupted by the insertion or deletion of one or more nucleotides, provided that the number of nucleotides added or removed is not a multiple of three.
