Why Dna Is Important In Forensic Science

DNA is very helpful in forensic science. Forensics is the scientific study of evidence for crime scene investigators and any other legal proceedings. The study of DNA samples to determine whether they come from the same individual is known as DNA profiling. DNA profiling can help assist crime scene investigators identify an individual. To match DNA, scientists usually compare sequences in the genome that varies from person to person. DNA profiling has become an essential tool in forensics. For example, DNA profiling first attracted people’s attention during the O. J Simpson murder trial case. DNA analysis proved that the blood found in Mr. Simpsons car belonged to the victim and also that the blood at the crime scene belong to Mr. Simpson. DNA profiling can also be used to identify murder victims. For example, after 911 took place, DNA profiles of tissue samples were matched from the disaster site were matched to DNA profiles of tissue known to be of the many victims. DNA profiling also extends beyond crimes. For instance, comparing the DNA of a mother, her child, and the alleged

One of biology’s major goals is to explain how such diversity arises while also accounting for characteristics common to different species. For example, the universal genetic language of DNA is a form of how biological diversity arises. This basic language joins all the kingdoms of life. Biodiversity can help boosts an ecosystems productivity. One example of biological diversity is the rainforest. It has so many different types of species within it that it is considered to have biological diversity. A local pond is also another example of biological diversity. If you could take a closer look within the pond you can locate several species that share the same home. Deserts, rainforests, and coral reefs are examples of biologically diverse
