Crime Scene Investigation: Cindy was attacked by a masked assailant but she managed to scratch him and get away. Three suspects were apprehended and their DNA samples were cut by the same restriction enzyme and then run through a gel. 1. Whose DNA matches the skin under Cindy's fingernails? 2. Why do some DNA piecestravel farther in the gel than others? 3. Why is important to use the same type of restriction enzyme when cutting all the DNA samples?

Crime Scene Investigation

A crime scene refers to a place where a crime has occurred. The purpose of crime scene investigation (CSI) is to analyze the complete scene and catch the culprit based on the pieces of evidence collected from the place of crime. The people involved in this process are referred to as crime scene investigators.
