Use food coloring in electrophoresis. The last segment in a four-part series mimics DNA fingerprinting by using chromatography. Teams conduct chromatography on food coloring to find colors that use similar pigmentation in their makeup.

Police find a man murdered in a local hotel, DNA everywhere, and now they need scholars' help. Budding detectives step into a crime scene playing the roles of victim, suspects, and investigators. They apply knowledge of criminology and...

DNA carries the codes for creating just the right protein. A well-designed lesson leads pupils through the process from start to finish and everywhere in between. Guiding questions with supporting video help scholars understand the...

Different types of mutations cause unique types and degrees of muscular dystrophy. Scholars learn about the types of mutations and the impact on the body. They compare the location of the mutations and draw conclusions about how it is...

Silver: more than jewelry, it's also a natural antimicrobial agent. An inquiry-based lesson asks collaborative groups to design and implement an experiment to test this property. Using samples of silver nanoparticles and a strain of...

This lesson plan can be used to illustrate the principle of electrophoresis without the equipment. Paper chromatography can be used to separate dye just like electrophoresis will separate DNA. The lab also covers DNA analysis for an...

Investigate how the genetic code on a DNA strands controls what protein is produced with this collection of animations and 3D models. Explore an interactive 3D model of the double helix, watch an animation of transcription, and see the...

Discover what controls how fast tiny molecular motors in our body pull through a single strand of DNA. How hard can the motor pull in a tug of war with the optical tweezers? Discover what helps it pull harder. Do all molecular motors...

Simulations of common biotechnology techniques performed in a laboratory setting. Learn how to complete these techniques and what task they are used for in the lab.

A simulation where students flip coins to mimic how parents pass genetic traits to their offspring through heredity. This activity also illustrates the difference between dominant and recessive genes, and how they interact with each...

You may have read about criminal cases where innocent people have been wrongly convicted of a crime. Sometimes, modern DNA analysis techniques have provided the evidence to exonerate these innocent people. In many cases, mistaken...
