You can use electrophoresis on segments of DNA which basically breaks up the amino acids into groups of particular ones, and then you can do the same to another DNA and compare them.
This works because your put enzymes on the DNA that eat the amino acid sequences in only some places, leaving groups of them. DNA of the same type would hold the same amino acids left.

all good. even as a criminal does something undesirable, as an celebration, murders someone, he consistently takes something from the crime scene and leaves something. This something he leaves can be a fingerprint, hair, or blood. If he dosent go away this stuff thats an complete different tale. yet, the police then do an intensive search for of the crime scene. in the journey that they locate something, they carry mutually a pattern of this and then they call in suspects, or take it lower back to their lab. Now, if the guy who dedicated the homicide has been in penitentiary earlier, something is matching the DNA to the suspect. yet when not, police get suspects, info, and witnesses, and then they use the info to seize the killer. Now, fingerprints are required everywhere in u.s., so in the journey that they locate a fingerprint, the killer is screwed.
