DNA Profiling

Improved Essays
Every human in this world has deoxyribonucleic acid (DNA), which gives humans their very own unique individuality. Determining personal characteristics from eye color to height, DNA is the genetic code to the human body. Every person carries about three billion DNA bases in each cell and the DNA in each cell is virtually identical (Edmondston 1).Genetic testing is used to show the subtle changes between humans DNA to form each one 's individuality. As time goes on, fears about the privacy of DNA has patients fear genetic testing and even refuse to get genetically tested. Understanding what Deoxyribonucleic Acid (DNA) profiling on humans is and the benefits and privacy of it can help inform whether it should be established or not. Over the …show more content…
Some may say, conventional fingerprinting is part of DNA profiling but they actually have great differences. Even though, fingerprinting may be the easiest way to identify a person, there are many limitations to it over DNA profiling.
Today, criminals are aware that fingerprinting relies on the presence of a finger impression and wear gloves. In contrast, DNA shed at a crime-scene can be extracted from many sources and used to generate a DNA profile (Edmonston 2).
Edmondston goes on to say, DNA can be extracted from one single cell, including from partial fingerprints that can not be identified and fingerprints also can not be obtained after any type fire or bombing in any type of crime-scene.Any technique that is used to identify someone is very useful in discovering who that person is or if someone was part of the crime committed but overall, DNA profiling is the best technique over conventional fingerprinting when fingerprinting is

With the use of DNA profiles, suspects can be narrowed down by a process of elimination. DNA evidence is a great tool in search for justice and can help prove innocence or guilt. In sexual assault and murder cases, investigators are able to profile the suspect 's DNA by hairs and fibers from clothing, carpet, bedding, or furniture that was left behind (Edmondston 13). DNA profiling is not just used in humans, but in animals as well in animal breeding disputes for accounting false paternity of animals for sale in the market according to Edmondston. As for humans, identification of biological remains damaged beyond recognition can be used in reverse of the principles applied to paternity testing. In other words, this can be helpful in the identification of bodies after death combat, by taking DNA samples from blood relatives to compare to the bodies. DNA profiling is a major tool used to solve crimes and help serve justice to the

    Fingerprinting is used to test ones identify and assess the genetic information of individuals; it is not common for any two people to have the exact same physical fingerprint, which is why fingerprinting is done in forensic science (Houck and Siegel). By having a small drop of blood or the follicle of a hair it can contain plenty DNA that could be tested. There are other examples that contain DNA such as semen, hair, skin scrapings and buts of cigarettes are also often used in criminal investigations. When crimes have to be solved in forensic science; blood semen, skin, and other forms of tissue that can be found on a crime scene can and will be analyzed to prove whether a suspect was there or not and if he or she has committed a crime that they have been accused of. It can also be useful in identifying a body.…

    Despite this, small samples are sent to multiple independent labs, which helps to reduce the possibility of an error which affect the final results. As DNA evidence is being passed through multiple labs, the individual’s private DNA information has the potential to be used in different crimes. However, it is stated in an article on “Forensic Databases: benefits and ethical and social costs” that, “Public support has been presumed on the grounds that all law-abiding people want criminals to be caught and convicted and the ‘innocent’ have nothing to fear from DNA technology.” (Forensic Databases: benefits and ethical and social costs, British Medical Bulletin, 2015). It is clear that most of society demands for criminals to be found and people who are deemed not guilty should have nothing to worry…

    Based on the existence of biological evidence, DNA tests is vital in ensuring that the criminal justice system is fair and accurate (justice.gov, 2014). DNA in Forensics can be used to identify criminals in cases where the suspect is known and also in cases where the suspect is not known. For example, DNA sample from a suspect who has been arrested can be directly compared with DNA sample from the crime scene; on the other hand, DNA samples from the crime scene can be matched with DNA samples archived from other crime sense and already prosecuted cases. Although the DNA collection and analysis system needs great improvement, the system has been used successfully used to prevent the most heinous and violent crimes form taking place and has also helped convict most dangerous criminals involved in a series of different crimes (justice.gov, 2014). In cases of aggravated assaults, the use of DNA in forensics has helped provide evidence for most cases that had no witness available.…

    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…

    Criminalistics, while often called forensics, is actually a subdivision of forensic science that encompasses a wide variety of scientific disciplines, such as toxicology, anthropology, and odontology. The primary purpose of this field is to identify, gather, analyze, and interpret physical evidence found at a crime scene, as well as present it in court. The gathering and analyzing of evidence is paramount to forming a case, prosecuting the perpetrator, and convincing the judge and jury. Without relevant physical evidence, there would be little else to present in court other than eye witness statements and testimonies provided by the defendant and plaintiff. Physical evidence provides the most accurate portrayal of a crime and can directly link…

    The scientific errors that can occur in DNA profiling is minimal and the sequence used to determine the individual is very concise. Because of this DNA has been used as evidence to help capture perpetrators and even clear innocent people of the crimes committed. Most people share similar DNA sequences, but some areas of DNA are specific to each person. The areas in which are specific to each person are the location that forensics localize in when catching a perpetrator. For instance, the FBI’s forensic DNA identification system studies thirteen regions in the genome.…

    “All the hereditary information of an organism makes up it genome.” The genome of an organism is partially determined by the sequence of bases. The Human Genome project was founded 1990 and had a major goal of identifying and mapping all of the genes in human DNA, numbering about 20,000-25,000 genes and about 3 billion chemical base pairs. This project was completed in 2003 and contributed to the development of our modern knowledge of human DNA. This information is available to scientists worldwide and has prompted the researching of the genomes of several different species. This information can help determine the health of human by comparing abnormal DNA sequences with that of a typical DNA sequence.…

    Introduction Several countries around the world maintain a database dedicated to storing DNA profiles of individuals. The primary purpose of a DNA database is to ease the identification process of suspects during criminal investigations. Despite the intention to do good, the concept of a DNA database is vulnerable to a number of complications and repercussions, affecting the government, general public and crime detectives. Biological Significance DNA Profiling is a forensic process utilised to identify individuals by the characteristics of their DNA. It differentiates from other forensic identification processes because it remains the same overtime, unlike fingerprints and has a higher accuracy than biometric iris scanners.…
