Reflection: Complex Tasks Modeling Replication (Part 1/2) - Section 4: Student Activity: The Meselson-Stahl Experiment (Conservative Model?)

 

Without a hands-on activity, this modeling experiment can be very difficult for students to understand.  Using a model building exercise, students evaluate the results of the experiment based on the three possibilities for DNA replication. By understanding what the results should be based on particular model certainly aids students in identifying the proper model once they learn the results that Meselson and Stahl got from their actual experiment.  In this video, I review the rules of the game to my class.

Modeling Replication (Part 1/2)

Unit 12: Molecular Genetics
Lesson 4 of 7

Objective: Students will evaluate data to determine which model best explains how DNA replicates.

Big Idea: Recreate Meselson and Stahl's experiment through this simulation to determine how DNA copies itself.
