DNA fragmentation is the separation or breaking of DNA strands into pieces. Why is it important to identify different DNA fragments in DNA profiling? You and your team have taken a magnifying glass to look at the evidence so that you can compare it to the DNA of the 4 suspects. Which suspect do you think committed the crime based on the results from the gel electrophoresis? Use evidence from the diagram and what you know about the process to justify your response. How is the evidence from earlier years vs. evidence used now changed? Evidence DNA Suspect #1 Suspect #2 Victim Officer

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.
