The evidence of this lab has given me the conclusion that Dr. Ward has been murdered. The primary suspect based on the research of the crime scene would be Miss White, his secretary. The purpose of this lab was to allow the class to experiment with DNA samples as well as fingerprints and hair samples to come to a conclusion of who had killed Dr. Ward based on our own experiments and research. The main pieces of evidence leading to Miss White(S3) being the primary suspect are the hair samples as well as fingerprint 2 on coffee cup.

After its melted and you don’t see any clumps you pour it into the mold to cast the gel and wait 20-30 minutes for the gel to set. Plug in your electrophoresis system and assemble the platform in the tank. After the gel sets remove it from the casting stand, setting the gel tray inside the tank on the platform making sure the wells are facing the negative side. Measure out 125 ml of diluted SB running buffer and pour slowly into one side of the tank, removing all air bubbles. Turn on the low intensity light and load your DNA samples using 10 μl per well, changing your pipette tip after every sample. Put on the photo hood and press the power button which activates a green light, let the gel run for 25-30 minutes or until DNA separation is sufficient. Use the photo hood to take a picture with a cell phone or camera. Fingerprint 1 is a mixture of prints and can not be depicted on who it belongs to. Fingerprint 2 is a whorl print, it can belong to Miss White. Microscope Image of Hair 1 is from a cat, belonging to Dr. Powell’s cat or Miss White’s Boyfriends cat.
