Product Details

Learn how to isolate DNA from human cells—yours! DNA can be isolated from many types of tissue. In this activity, students extract DNA from their own cheek cells. The procedure for securing student cheek cells is safe and requires only a rinsing of the mouth with water. Isolating “personal” DNA adds a great deal of student interest to a lab that otherwise might be less than exciting. Note: The procedures detailed in this kit can be used to “spool” DNA from many different sources other than cheek cells.

HS-LS1-1. Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins, which carry out the essential functions of life through systems of specialized cells.
HS-LS3-1. Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.
