Question

Investigator Robbins is charged with collecting DNA from a crime scene. What piece of evidence would not be useful for DNA testing?

Saliva from a discarded cigarette butt
The suspect's boot prints in the mud
A stray hair found clasped in the victim's hand
Tape used to cover the victim's mouth

Answer 1

The suspect's boot print in the mud.

Explanation:

The boot print in the mud is by-far the least likely to carry any samples of DNA or other genetic materials.

Answer 2
