A buccal swab collects a sample from which location?

Explanation:
A buccal swab is used to collect cells from the inside of the mouth, specifically the buccal mucosa on the cheek. The swab is rubbed along the inner cheek to gather epithelial cells and some saliva, which are then used for DNA analysis. This method is noninvasive and quick, which is why it's preferred for genetic testing and similar purposes. It does not collect materials from blood, stool, or urine, which come from different body sites and require separate collection methods.
