What is the purpose of the protein fingerprinting kit?
The Protein Fingerprinting Kit is designed to study the evolutionary relationships among fish. A family tree of fish evolution is provided as part of the documentation, and the electrophoresis pattern (gel results) is compared in the final steps to the fish family tree. Thus the student sees that biochemical gel patterns can be used to confirm and to posit family relationships among fish species.
Traditional systematics and taxonomy posits relationships based on morphological and behavioral traits, and puts species in relation to each other in the traditional classifications: kingdom, phylum, class, order, family, genus, and then species.
Biochemical traits are the result of structure and function of the proteins involved. The character used here is the molecular weight of the proteins.
