The Case of the Missing Necklace
Students solve a crime using paper DNA strips to model gel electrophoresis. This can be used as an introductory lab for a later gel electrophoresis lab or be used to introduce the process of gel electrophoresis.
This activity was selected to give students basic concepts that are vital for understanding agricultural biotechnology:
- Different organisms have different DNA sequences.
- The four nucleotides can create a large number of sequences.
- DNA can be manipulated and identified by using laboratory techniques.
- Restriction enzymes can be used to cut DNA strands.
