Biology: Traveling Blue Genes

by Texas Instruments - Simulation Lesson


  • Students will observe a time-lapse simulation of the process of DNA Gel Electrophoresis.
  • Students will electronically measure the results of gel electrophoresis and then graph, and analyze these results.
  • Students will discover the effects of time, voltage, and agarose gel density on the results of gel electrophoresis.


  • DNA gel electrophoresis
  • double helix
  • interpolation
  • extrapolation
  • nucleotide
  • phosphate
  • deoxyribose
  • restriction enzymes

About the Lesson

This lesson involves students using TI-Nspire technology to simulate, observe, and manipulate the variables that affect the results of DNA gel electrophoresis.
As a result, students will:

  • Reinforce understanding of the structure of DNA;
  • Understand the process of gel electrophoresis;
  • Recognize the effects of time, gel density, and voltage on the outcome of gel electrophoresis.
