In the original sequence, the codon ATG codes for the amino acid F1, AAT codes for F1, and CAC codes for S1. In the mutated sequence, the AAT codon is changed to AAG, which codes for a different amino acid (F10 instead of F1), resulting in a missense mutation. If there were a different nucleotide insertion or deletion that shifted the reading frame, it would be a frameshift mutation, but that is not the case here.
