DNA Fingerprinting for High School Biology
Learners work with tools and techniques used in genetic engineering. They dissect a sample into fragments of DNA using restriction enzymes, sometimes called "molecular scissors". They sort these fragments, measure and analyze them according
Curated OER
lambda DNA Fingerprinting Simulation
Students perform restriction digests on DNA samples from four individuals, and then search for similarities between the individuals by running the restriction fragments on an electrophoresis gel.
Curated OER
Gel Electrophoresis: Sort and See the DNA
Students construct DNA fingerprints. In this genetics lesson, students watch an on-line gel electrophoresis animation, then they work in groups to use a restriction map to create a restriction enzyme and use that to arrange a DNA...
