Bring any questions you have to chat. Then return and attempt the exercise as many times as necessary to achieve an 85% or better score.

Lab Exercise

Lab Instructions: Complete the DNA Analysis lab.

Labs are within two weeks of the discussion section; the extra time should allow you to find equipment or materials. Post your lab results to the class Lab forum, in the appropriate thread.
