Lesson Plan: Applications of DNA Fingerprinting Biology

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to outline the basic principles of DNA fingerprinting and recall some applications of it.


Students will be able to

  • understand that the majority of DNA in eukaryotes does not code for proteins,
  • describe how DNA fingerprinting compares the noncoding, repetitive sections of DNA within individuals,
  • describe how DNA fingerprinting can be used in forensic investigations, paternity testing, and identification of closely related organisms.


Students should already be familiar with

  • the fact that DNA contains the genetic material of an organism.


Students will not cover

  • cloning DNA sequences (PCR),
  • gel electrophoresis.
