Electrophoretic Analysis: DNA Fingerprinting and Evolutionary Divergence
Students examine the principles of electrophoresis. They evaluate both the agarose and polyacrylamide system of molecular separation. In order to bring the concepts of genetics and evolution full circle from DNA to protein, students...
Curated OER
Identification of Animals by Serum Electrophoresis
Students compare their unknown serum against a set of known serum standards and determine the animal source of their serum. They write a lab report to communicate their results.
Curated OER
Gel Electrophoresis Simulation
Learners identify the steps in a gel electrophoresis experiment and describe the role of enzymes. They examine the relationship between fragment size and migration rate in a gel. They view DNA fragments as well.
Curated OER
Outbreak! Electrophoresis: Where the Bands Are
Students examine why pieces of DNA move at different rates and over different distances. In this DNA lesson students complete an activity.
Curated OER
Build an Electrophoresis Chamber
Students explore electrophoresis, a technique used to isolate DNA. They assemble a gel chamber for separating mixtures. Students observe separation influenced by electric charge. They define separation through gel electrophoresis.
Curated OER
Molecular Evolution in Plants
High schoolers are using a paper chromatography study that is suitable for introductory biology. The absorption spectra studies and gel electrophoresis studies are appropriate for students who have complete both introductory biology and...
Curated OER
The Electrophoresis of Human Hemoglobin
Students analyze different types of hemoglobin. They use the technique of agarose gel electrophoresis to separate human hemoglobin molecules according to their electrical charge, size, and/or shape. Students relate the migration of...
Curated OER
Proteins Expressed At Different Stages
Young scholars investigate protein electrophoresis in a lab setting. Full laboratory equipment is needed and safety should be taught. The level of prior knowledge needed to perform lab is high and is ideal for an honors class.
Curated OER
DNA Fingerprinting through a Chemistry Lens
Students explore DNA and restriction enzymes using fragments of DNA separated by electrophoresis on an agarose gel. They analyze the results to see "whodunit".
Curated OER
Extraction of DNA from White Onion
Pupils investigate techniques involved in extracting and isolating DNA. Students extract and observe onion DNA.
Curated OER
DNA Fingerprinting
Pupils experiment with chromatography as a technique which is similar to electrophoresis that scientists use to identify DNA samples.
