Wolf Pack in a Bottle: DNA Simulation with Paper Chromatography

Author/Source: Sullivan, Aleta
Overview:This lesson uses paper chromatography to simulate electrophoresis of DNA. The problem posed is to identify the genetic similarities among several sub-species of wolf in order to provide information for a conservation/breeding program.
Concepts:This lesson covers the following concepts:
  • Scientists use the similarity of DNA nucleotide sequences to infer the relatedness of taxa.
  • As with other scientific disciplines, evolutionary biology has applications that factor into everyday life.
