B) A deletion mutation
C) A frame-shift mutation
D) A nonsense mutation
E) A missense mutation

Question

Quizplus · Accepted Answer

A missense mutation is a type of point mutation where a single nucleotide change results in a different amino acid being encoded. This affects only one amino acid in the sequence. A silent mutation and a nonsense mutation may also result from a single nucleotide change, but they do not always result in a change of the encoded amino acid. A deletion mutation and a frame-shift mutation may affect multiple amino acids in the sequence.
