On police procedural tv shows, the brilliant detective sometimes gets a dna sample from a paper coffee cup that the suspect has touched. is this fantasy made up for television, or is it scientifically sound?

The correct answer will be- it is scientifically possible

Explanation:

Taking the DNA sample from the coffee cup in solving the criminal cases can be performed.

This could happen as touching the cup can help extract the DNA sample as the act of touching leave few cells which can provide the minute DNA sample. This sample can be replicated via PCR technique which could help solve the case. The case can be solved by comparing the DNA samples of the suspect and the collected samples.

Thus, it is scientifically possible is the correct answer.
