Which of the following is NOT a frameshift mutation? A. Deletion
B. Insertion
C. None of these
D. Inversion

The type of mutation that is not a type of frame-shift mutation is inversion.

FRAME-SHIFT MUTATION:

A frame-shift mutation is a kind of mutation that causes the manner in which a nucleic acid sequence is read in the genetic code. Frame-shift mutation can occur via two major means as follows: deletion and insertion. Deletion mutation occurs when a nucleotide base is removed from the sequence while insertion mutation occurs when a nucleotide base is added to the sequence. Deletion and insertion causes the sequence of nucleotides in DNA to be shifted. Therefore, the type of mutation that is not a type of frame-shift mutation is inversion.
