MISTAKES IN DNA A MISTAKE CAN BE 1 A point mutation substitution addition or removal of a single DNA base 2 A frameshift mutation a point mutation due to an addition or deletion of a DNA base that causes a major change in the genetic code. GENETIC MUTATIONS. MISTAKES IN DNA. A MISTAKE CAN BE:. 1. A point mutation – substitution, addition, or removal of a single DNA base.. 2. A . frameshift. mutation – . a point mutation due to an addition . Human chromosomes. Most cells in your body normally contain 46 chromosomes, organized into 23 pairs. In each of these 23 pairs, you've inherited one chromosome from your father and one from your mother. . Jessica Hawley. Compiled . By: . C. Kohn, Waterford, WI. Objectives.
