Imagine you are a forensic

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

I would answer the student by explaining that while humans share a similar genetic makeup, our DNA is unique and can be used to differentiate individuals, making it a reliable tool for identifying suspects and determining their innocence or guilt in a crime.
