Blood, saliva, hair, skin. Any of these parts from the human body can be used during DNA profiling no matter what amount is found. DNA profiling is the analysis of DNA from samples of body tissues or fluids in order to identify individuals. Mostly used to convict criminals (murder, rape, kidnapping, etc") . But also it can be used for kids looking into their family heritage. It is extremely important to have this biotechnology because without it the world would be a much more violent place.
With the right forensic analyst, DNA profiling can be a quick easy process by following these steps: First a blood, saliva, hair, etc.. must be collected. Then the forensic analyst must use a method called Polymerase Chain Reaction (PCR) to make millions of copies of revealing DNA. After PCR the forensic analyst must count the repeats/copies so the region can be distinguished from others. Then the mixture is run through a capillary electrophoresis machine. Last the scientist must look for a match in his/her STR repeats. This will distinguish the person of interest.
I am strongly for the use of DNA profiling. I think without it the world would be a much more violent, scary place to live in. There are many times in history where DNA profiling prevents murderers from killing.
Some people think that DNA Fingerprinting is infringe upon privacy and civil liberties, and also if a person with a certain race is convicted there is a discrimination of against race.
I strongly am for the use of DNA profiling. Almost 99% of the time DNA profiling works. Even if the testing leads you to the wrong person you will still have a person of interest for the crime. If we were to stop using DNA profiling crime rates would increase drastically. Since the 1980"s when DNA profiling was established, the crime rate has dropped remarkably. There are so many times when DNA profiling solves the crime because the criminal almost always leaves the right evidence. And yes, DNA does degrade over time but is there many times when police are too late? Not really. And police forces always hire the best DNA analyst for the job. Oh, and what if you're a kid wanting to know about his family heritage? It is extremely simple, all you need to do is leave it to DNA profiling and the analyst. There are many cases won by the use of DNA profiling. For example, a 1988 murder of a women named Georgina Pacheco. The body was found by an officer and reported immediately. They police force couldn't solve the case until they had the right technology in 2009 which told them Robert James Parks was the suspect in the murder.
DNA profiling is oftenly used for children looking into their family heritage Without DNA profiling, adopted children would never be able to find their legitimate parents. It would be impossible without it. This is yet another great use of this great technology..
