DNA Extraction Lab

In my practicum, I was fortunate to have had the chance to teach a very small class of grade 12 biology students.  I wanted my very first class to be a fun one to help build rapport with the students before delving into the more challenging material of the molecular genetics unit that I was teaching. The activity that I chose to do was a strawberry DNA extraction. This activity is quite simple and can even be done with younger students to get them interested in DNA structure.  For the grade 12 university biology class, this activity most directly addressed specific expectation D2.3 of the molecular genetics strand:  Conduct an investigation to extract DNA from a specimen of plant or animal protein.
