What Is a Possible Consequence of a Mutation Affecting a Nucleotide

What is a possible consequence of a mutation affecting a nucleotide in a coding sequence of an mRNA molecule?

A) An incorrect amino acid is added to the growing chain,resulting in a defective protein that potentially does not function properly.
B) Protein synthesis comes to a full stop.
C) All the correct amino acids are represented,but the out-of-sequence chain results in a mutated protein.
D) The defective mRNA molecule does not move into the cytoplasm after transcription,therefore the protein is not synthesized.
E) The mutated nucleotide is skipped,shifting and regrouping the remaining codons to create a different protein.
