Explanation: Insertion and deletion result in a frameshift mutation. Frameshift mutations caused by "indel" mutations, meaning insertion or deletion mutations. These mutations shift the way the DNA is read. A frameshift mutation can throw off all of the nucleotide that follow in a DNA sequence, making them particularly likely to lead to significant consequences.
