This specific technique of biotechnology was developed by a British geneticist named Alec Jeffreys in the year 1984. Jeffreys’ noticed that minisatellites, certain sequences of highly variable DNA, which did not contribute to the functions of genes, were repeated within genes. (2016, Encyclopædia Britannica, Inc.) Minisatellite DNA, also called variable number tandem repeats (VNTRs), are made up of longer repeats blocks that are spread throughout the genome. (2016, Encyclopædia Britannica, Inc.) DNA fingerprinting is widely known to be used in criminal investigations. To see how well a suspect’s blood or any bodily material is closely related to evidence that may have been found on the crime scene, DNA fingerprinting allows investigators to evaluate just how well they match. Established in all states, there are DNA fingerprint databases, which all states require the collection of DNA from convicted felons. In order to insure that the information is accurate, there is a procedure that has to be completed in order for it to be a reliable forensic …show more content…
It is amazing how a drop of blood or even a spec of hair from its root can contain more than enough DNA for testing. Although the usage of DNA fingerprinting has highly advanced since its discovery, there is still some controversy just like anything else big and/or major. Some people think that this biotechnology tool can be a violation of privacy while others see it as a helpful and safe tool. I myself think it serves a sense of justice. For instance, some individuals are wrongfully convicted of a crime in which they were accused of. However, DNA fingerprinting helps reveal the truth accurately and gives that wrongfully imprisoned person another chance at life. Other cons consist of people being worried about being negatively profiled. Because our DNA holds some pretty significant information about us, some individuals see it as one of those cases where people judge you before even meeting you. We all can imagine how painful that can feel and even affect our lives one way or another. Some positive things DNA fingerprinting provides is a peace of mind, helps to determine hereditary diseases, and even makes identification easier when accurately and efficiently done. However, it could be negatively viewed depending on the
