LECTURE 9 Frameshifts, deletions and dynamic mutations. 1. Frameshifts. a. Frameshift mutation are caused by the addition or subtraction of nucleotides from the DNA sequence. Because the genetic code is read in triplets, addition or subtraction of 1 or 2 nucleotides causes a shift in the reading frame.rameshift mutation are caused by the addition or subtraction of nucleotides from the DNA sequence.
