The Uses of DNA Technology in Forensic Science Essay Example for Free

The Uses of deoxyribonucleic acid Technology in rhetorical Science EssayTimothy Banas has a masters degree in biophysics and was a high school science teacher in Chicago for seven years. He has since been working as a trading systems analyst, standardized test item developer, and freelance writer. As a freelancer, he has written articles on everything from personal finances to computer technology. Forensic science haves the use of scientific procedures to realize evidence related to matters of the law. The cells of all organisms contain deoxyribonucleic acid ( deoxyribonucleic acid), and the DNA of any one organism is unique. Forensic scientists have learned to collect and analyze DNA to help determine which organismshu small-arms as well as other kindswere present at the scene of a crime or catastrophe. DNA rout out be used to accomplish a number of specific goals in rhetorical investigations. Identifying Individual Persons* Because each persons DNA sequence is unique, i t can be matched to him like a fingerprint. According to the U.S. governments Oak Ridge National Laboratory, forensic scientists use DNA evidence to place persons in criminal and paternity cases. DNA evidence does not always identify a suspect or a man as being the aim of a child sometimes the forensic evidence exonerates a suspect or determines that a man is not the father of a child. DNA evidence can also be used to identify victims of catastrophes, such as natural disasters or terrorist attacks.Identifying Species of Animals* There are laws governing the conservation and hunting of be species. If someone is suspected of illegally capturing and transporting an endangered species, forensic scientists can use DNA analysis to actualise or rule out whether the animal specimen in question in fact belongs to the saved species. A few hair or skin cells from the animal will suffice to yield absolute test results, so a suspected animal transporter or hunter does not privation to be ca ught with the actual animal.Other Applications* DNA evidence can be used to identify a type of bacteria or parasitethat may have caused the death of a person. This information can be useful in cases of medical or parental negligence. The origins of expensive consumables like liquors and caviars can be verified using DNA analysis. Lastly, DNA samples can help medical professionals find good presenter organ matches for people who require organ transplantations to survive. -BioremediationThe use of living organisms for the recovery/ cleaning up of a contaminated medium (soil, sediment, air, water). The process of bioremediation might involve introduction of new organisms to a site, or enrollment of environmental conditions to enhance degradation rates of indigenous fauna.Bioremediation can be applied to recover brownfields for tuition and for preparing contaminated industrial effluents prior to discharge into waterways. Bioremediation technologies are also applied to contaminated wa stewater, ground or surface waters, soils, sediments and air where there has been either accidental or intentional release of pollutants or chemicals that generate a risk to human, animal or ecosystem health.Different approaches to bioremediation take advantage of the metabolic processes of different organisms for degradation, or sequestering and concentration, of different contaminants. For example, soil bioremediation might be performed under either aerobic or anaerobic conditions, and involve optimization of the metabolic pathways of bacteria or fungi for degradation of hydrocarbons, aromatic compounds or chlorinated pesticides. Phytoremediation is bioremediation using plants and is much proposed for bioaccumulation of metals, although there are many other different types of phytoremediation.Bioremediation using genetically engineered microorganisms (GEMs, or GMOs), carrying recombinant proteins, is still comparatively uncommon due to regulatory constraints related to their rel ease and control. Other methods of enzyme optimization that do not take on gene cloning technqiues, might beapplied to indigenous microorganisms in order to enhance their preexist traits.ExamplesNutrients were added to the soil to enhance bacterial degradation of contaminants and increase the rate of bioremediation on the brownfield site.
