Question

Imagine you are a forensic investigator giving a presentation to a school assembly. A student asks you, “If people have such similar genetic makeup, then why do you use DNA to understand whether suspects are innocent or guilty of a crime?” In 1 - 2 simple sentences, describe how you might answer the student’s question

Answer 1

DNA can help us identify unique features in a person's genetic code that differentiate them from others, allowing us to determine if they were present at a crime scene and thus aiding in determining their involvement in the crime.
