About This Simulation
Solve a crime by using DNA fingerprinting to identify a thief. Use nucleic acid gel electrophoresis to separate and visualize DNA molecules and watch an animation to understand what happens inside the gel tank.
Learning Objectives
- Explain the visualization and separation of nucleic acid molecules through gel electrophoresis
- Summarize how nucleic acid molecules migrate through an agarose gel
- Explain the principles behind size separation and direction of migration
- Analyze and interpret a nucleic acid gel by using a DNA ladder and controls
About This Simulation

Learn More About This Simulation
Your peanut butter keeps getting stolen and it is time to catch the thief. In this simulation, you will learn how you can use DNA fingerprinting to identify individuals. You will use gel electrophoresis to separate and visualize DNA fragments.
Loading the gel
Join Dr. One in the molecular biology lab. The DNA samples from the crime scene and two suspects have already been collected, extracted, and amplified for you. You will start by learning about sample preparation and loading the samples into an agarose gel with a pipette.
Look inside the gel
Once you have loaded all the samples into the gel, you can start the gel electrophoresis process. While this runs, you will dive into the gel tank and discover how DNA fragments are separated by size with this technique through an immersive animation.
Analyzing the gel
Now that you understand how gel electrophoresis works, you will return to the molecular biology lab. The DNA fragments have now been separated and visualized so you can compare the band patterns of the two suspect samples with that of the crime scene sample. Will you be able to catch the thief?

For Science Programs Providing a Learning Advantage
North Dakota State College of Science
“They did the simulation at home, then completed the in-person lab within 30 minutes, no questions asked, and passed the quiz with flying colors.”
Lecturer in Human Physiology
University of Westminster
"I saw some of the students who clearly didn’t necessarily like sitting there reading a book discover they could turn on Labster and keep up with the rest of the class because it spoke to them.
Modesto City Schools
"Having something that's engaging for the students gives teachers that opportunity to breathe and get excited again. Because they're seeing the kids light up, they're seeing the kids engage with content."
Wenatchee Valley College
"The question always is, ‘Can we demonstrate that the students are meeting course outcomes?’ Check! We can do that.”
San José State University
"We surveyed over 400 students. More than 90% thought Labster was easy to navigate, and that it was fun, but more importantly, most of them felt confident that they could execute the labs in person. And that confidence is a big deal."
