1

Compare the mutated DNA sequence to the original. Identify the mutation as either an insertion, deletion, or substitution, and whether it is a frameshift or point, and whether it is a silent mutation.

Original DNA Sequence: T A C A C C T T G G C G A C G A C T

Mutated DNA Sequence: T A C A T C T T G G C G A C G A C T
