Why is a cheek swab a good way to collect DNA?

A cheek swab is a good method for collecting DNA because it is non-invasive, quick, and easy to perform. It involves using a cotton swab to collect cells from the inside of the cheek, which are rich in DNA. This method minimizes discomfort and risk compared to blood draws or other invasive techniques. Additionally, cheek swabs can be easily stored and transported for analysis.
