DNA Fingerprinting with Restriction Enzymes
Students will illustrate how restriction enzymes work by piecing together parts of a puzzle. Then they apply this knowledge to help them analyze genetic evidence from the scene of a crime as well as to help them comprehend how a DNA...
Curated OER
DNA Fingerprinting
Ninth graders investigate what restriction enzymes do, and explain how a DNA sample can link a suspect to a crime.
