er cells in the body. Another extremely crucial characteristic of DNA is that everyone has his or her own unique DNA. Since people in general basically are alike in that we all have legs, arms, hearts and brains it is easy to see that most DNA is identical. The key to identifying individuals through DNA is not through the strands of DNA that have a known function, rather it is the DNA that has no known function. Inside these strands of DNA with no known function, called Junk DNA, are different repetitive DNA patterns, which are unique from person to person. This is why DNA can always be traced back to one person (with the exception of identical twins)(Levy). There are a great number of reasons to have a DNA data bank, but first it is important to accurately describe the requirements for this DNA data bank. Only convicted criminals would be entered in the bank. Also, only Junk DNA would be kept as data, DNA that contains no personal or hereditary information. One advantage to a data bank will be the quick access to information. Prosecutors are going to be able to match the DNA collected at a crime scene with DNA that has already been collected in the bank and this will allow them to apply for a warrant faster (Billings). Take the case of Jean Ann Broderick. In 1991 she was found murdered and raped in her Minnesota apartment. There were no witnesses or evidence that led to any one suspect. The only lead at the crime scene was a semen stain on the victim. Minnesota at this time was one of the few states that had and used a DNA data bank of convicted criminals. The Minnesota authorities checked their sample DNA with the DNA data bank and found a match that linked the DNA with Martin Perez, a 37-year-old illegal alien. After the DNA identified Perez, he was also identified by witnesses, who had seen him with Jean Ann Broderick (Levy).Another advantage of having a DNA data bank is that it is much easier to identify repeat ...
