Can your class save the peas? In this scenario, they will test 5 different fields of peas to see if they are infected with a devastating plant pathogen using PCR.
Tests that look for the presence or absence of a DNA band must have an internal control to check the test has worked. A test for a constantly expressed “housekeeping” gene must be included.
Show how PCR can detect pathogens, electrophoresis and the importance of using a control in experiments.
