Using the table below,determine the kind of gene mutation illustrated.ATG_AAT_CAC  ATG_AAG_CAC 
A) missense mutation 
B) nonsense mutation 
C) frameshift mutation 
D) silent mutation

Quizplus · Accepted Answer

The change from AAT to AAG results in a different amino acid being incorporated (from asparagine to lysine), which is a characteristic of a missense mutation. The fact that the codon for histidine (CAC) remains unchanged rules out a nonsense mutation. There are no insertions or deletions of nucleotides, so a frameshift mutation is not occurring, and there is no change to the stop codon, so it is not a silent mutation.
