Have you ever wondered how police officers classify someone simply by taking a simple blood test? Well, DNA profiling is a method of identifying an individual based on the unique characteristics of their DNA. A specific DNA pattern is called a profile. It is obtained from an individual through a sample of tissue, blood, fingerprints, etc. DNA testing has many uses, both positive and negative, in our society. It also has many uses, in economic fraud prevention, dietary work and species classification, body identification, disease screening, and paternity investigations. More importantly, DNA profiling is used in forensic science to find out who committed the crime. Species classification is also an important use of DNA profiling. Growing databases of animal genes have given wildlife researchers and conservationists a powerful new tool to find new species and protect endangered animals. Scientists know the genetic profiles of some species so well that they can distinguish the region or population they come from by examining an individual animal's DNA. Genetic profiling is used comprehensively for paternity testing due to its ability to determine with a high degree of certainty about claims of being a child's parents or grandparents. This will allow investigative agencies to include or exclude possible sources of DNA found in connection with a criminal investigation. It is also true that DNA profiling can only be used if a sufficient amount of DNA is present in the samples. Crime samples can be compared to a sample from a known suspect or to a database of DNA profile results from other scenes or convicted perpetrators. If there is a "match", the two samples may have come from the same person. By comparison, the generated profiles... middle of paper... drive the scientist crazy who might threaten to release this information. One of the main problems with the DNA fingerprinting process is that the sample can be easily ruined. The smallest pieces of genetic junk can contaminate DNA samples, rendering them unusable. This is a huge downside because if the scientist were to accidentally drop a single piece of junk, the entire test would be ruined and another test would have to be performed. In conclusion, DNA profiling is something that the police could use to identify criminals, but the average person should not have the need to obtain a profile. There are pros and cons of DNA profiling, but in my opinion DNA profiling should be avoided, but should be used for criminals, or people involved in sperm donation, etc. If the donor file were to be lost, then DNA profiling could be used to find out who they were.
