What is the purpose of using the Chelex beads while extracting the DNA at high temperature from your cheek cells? Group of answer choices   The Chelex binds cations like Mg2+ that are co-factors for nuclease enzymes which would otherwise degrade the DNA.   The Chelex denatures the DNA and makes the DNA single stranded.   The Chelex will bind the DNA tightly after the cells are ruptured, helping extract it from the cells.   The Chelex provides Mg2+ co-factors needed by DNA polymerase enzymes to make more copies of DNA

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.
