Answer 2

Silent mutation is a point mutation and not a frame-shift mutation.

MUTATION:

• Mutation is a change in the nucleotide sequence of a DNA caused by a mistake in DNA replication or by a mutagen.

• A point mutation is a type of mutation that affects or involves only one nucleotide base in the sequence.

• A frame-shift mutation is that change in the nucleotide sequence of DNA which affects the frame-shift of the nucleotides.

• Frame-shift mutation occurs when a nucleotide is added (insertion mutation) or removed (deletion mutation).

• Silent mutation occurs when the change in nucleotide sequence does not alter the protein produced by that gene. Silent mutation is a form of point mutation.

• Therefore, silent mutation is a point mutation and not a frame-shift mutation
