Answer
Hi,
Assuming that you question is on DNA analysis, the DNA fingerprint at the scene should match that from the suspect or DNA profile stored in database
Step-by-step explanation
DNA analysis compares and looks for any match in the DNA samples collected at a scene. The analysis gives a visual representation of the DNA left at a scene of crime. Using columns of dark-colored parallel bands, the DNA fingerprints is lifted and matched with that of a suspected criminal or to a database of DNA profile in the department.
Hope it helps!
