In DNA fingerprinting the probe is of the sample which we got from the crime site or of all the suspect?

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.
