Expert Answer

Probes are small fragments of minisatellite DNA tagged with radioactive phosphorous.
The probes only attach to the pieces of DNA that they are complementary.
This probe determines which DNA fragments can be seen at the end of experiment.
Basically, probe is a DNA profile of all the suspects which is matched with the sample DNA obtained at the crime scene.
