One in a Million

A detailed Summary of One in a Million


DNA fingerprinting (the use of a person's DNA to identify them) has become a hot topic in the field of law enforcement as well as the entire world. The controversy exists on whether or not it should be admitted in court as evidence at this time. Some experts believe that the present technology allows DNA fingerprinting to be used in cases for positive identification (proof that the DNA match was at the scene of the crime) because of the extreme unlikeness that a "tampered" tissue cell could come up with an exact match. The chances are stated to be somewhere between one in ten million and one in ten billion. Other experts believe that since there is no current standard for labs to test DNA samples and there is a possibility of great human error in a very complicated ordered set (DNA) that a positive identification could be


DNA fingerprinting is at a very impressive standard at this time for identify people and there is no doubt about whether or not it should be used in the future. At this point I would assume that a one in a million chance is enough to be admissible in a court of law for positive identification. I could not blame a state for not admitting it either.

made on someone who is far from the actual perpetrator. Both sides believe that DNA can identify a person, they just disagree on whether or not that is possible at this point in time.

DNA fingerprinting takes a sample DNA (victims, suspects, etc.) and counts the number of variable number of tandem repeats (VNTR) in a person's DNA string. The repeats for four or five common repeating "gene groups" are counted and compared to a known sample (again the suspect, victim, etc.) for a match up. This may sound like scientist
