Genes are switched to different places, deleted, or inserted into a chromosome.
The cell does not divide correctly in mitosis or meiosis and the daughter cells contain an unequal amount of chromosomes.
DNA bases are matched to an incorrect base, deleted, or inserted into a DNA strand improperly.

DNA framshifts are caused by ______________ (adding) or _____________ (removing) DNA. Frameshifts are usually not good for an organism and leads to death. Every amino acid brought by _________ before the mutation will be good but after deleting or removing DNA every _______________ made after is incorrect. So an incorrect protein is made.
