The DNA sequence 5′ ATGGGGGACACC 3′ encodes the amino acids Met Gly Asp Thr.A mutation changes the sequence to 5′ ATGGGGAACACC 3′ that encodes the amino acids Met Gly Asn Thr.What type of mutation has occurred?
A)frameshift mutation
B)missense mutation
C)silent mutation
D)nonsense mutation

Question

This is a missense mutation because the change in the DNA sequence results in the substitution of one amino acid (Asp to Asn) in the encoded protein, without affecting the reading frame or creating a stop codon.
