Application

We will again extract DNA from our cheek cells, but also, obtain cheek cell samples from relatives to see how much DNA we share.  We will review the process of obtaining cheek cells in class by the students obtaining their own, then they will be required to perform this process on their own at home with their family members.  We will then extract the DNA from all our samples and prepare it for DNA fingerprinting.  This exercise will take several class periods, but it will provide a basis for the procedures in the next lesson.
