The Science: (Please use your text as a reference for this question). One day you are home visiting your grandmother and she asks you about an article she read that details a murder conviction based on DNA evidence yet she doesn’t really understand it.

How do you explain DNA testing in a way she will understand?
After your explanation your grandmother asks you how this procedure is different from other types of evidence like eye witness accounts or hair analysis. What do you say to her?
