Categorize the three types of mutations

  • DNA bases are matched to an incorrect base, deleted, or inserted into a DNA strand improperly.

  • 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.

  • Chromosmal mutation

  • Mutation in the DNA code

  • Nondisjunction

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.
