Solution
Two causes of frame-shift mutation are deletion and insertion (addition) of a nucleotide in a DNA segment. These changes shift the reading frame of codons, altering the gene expression and amino acid sequence in the protein produced. Deletion removes a nucleotide, while insertion adds one, causing the frame shift mutation.
