4. The Mix-up Bloomington police ran gel electrophoresis on saliva sample outside the front door Bloomington police ran gel electrophoresis on saliva sample outside the front door Police were suppose to run the other saliva sample found near the cage but mixed it up with other samples they obtained from the crime scene. Police were suppose to run the other saliva sample found near the cage but mixed it up with other samples they obtained from the crime scene. Need your help to run the solutions through electrophoresis to find the other saliva sample. Need your help to run the solutions through electrophoresis to find the other saliva sample.

5. Gel Electrophoresis Technique used for the separation of DNA, RNA, or protein molecules using an electric field applied to a gel matrix. Technique used for the separation of DNA, RNA, or protein molecules using an electric field applied to a gel matrix. Performed for analytical purposes, in this case identification of the burglar. Performed for analytical purposes, in this case identification of the burglar. The direction of migration for the DNA on the electrophoresis is from negative to positive electrodes. The direction of migration for the DNA on the electrophoresis is from negative to positive electrodes.

6. How it works -Using an electric field, molecules can be made to move through a gel made of agar. -Molecules being sorted moved through space in the gel -Gel is placed in electrophoresis chamber, which is then connected to a power source -When electrical current is applied, the larger molecules move more slowly through the gel, while the smaller molecules move faster - The different sized molecules form distinct bands
