Introduction to Molecular Evolution
Experiment #21 from Investigating Biology through Inquiry
In this Preliminary Activity, you will (1) extract proteins from muscle tissue, (2) conduct electrophoresis of the resulting protein extracts, (3) analyze the results using Logger Pro, and (4) construct a cladogram using the results.
After completing the Preliminary Activity, you will first use reference sources to find out more about protein gel electrophoresis before you choose and investigate a researchable question. Some topics to consider in your reference search are:
- protein
- amino acid
- gel electrophoresis
- fish
- evolutionary tree
- cladogram
- phylogenetic relationships
- SDS-PAGE
- denature
- molecular weight
- dalton
- kilodalton (kD)
- Educational Standard
- International Baccalaureate (IB)
