Kane Waltman 2.18.09 Use of DNA in Identification Response I found the article in which Dr. Landers of MIT gives a lecture on the use of DNA in identification very interesting. Amazingly, two human begins are 99.9% identical. It is that last .1% that differs me from anyone else. Although its not that hard to understand, because in a genome of three billion letters, even a tenth of a percent difference translates into three million separate spelling differences. DNA Identification is incredibly useful in court and legal cases. If any piece of a human is left at a crime scene, whether it is hair, a nail, or a piece of skin. They can immediately prove if a suspect is innocent or guilty. There is also an immense database filled with every past criminals finger print. This is also helpful. The DNA Identification has been most helpful in rape cases according tio Dr. Landers, because of this most rapists plead guilty. Dr. Landers also describes a grandmother, Heidi, who’s family is kidnapped by the military. Her daughter was two months pregnant, Heidi was told that her daughters child was kept alive. For ten years Heidi looked for the child. When she finally thought she found the child, she went to court and demanded a DNA test. Dr. Landers does a fantastic job in his lecture to describe the uses and positive results of DNA Identification and PCR. He pulls your heartstrings to convey a point, using many examples from different time periods were PCR; was used, could have been used, should have been used. |
