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

    The two major uses for the information is for personal identification and for the determination of paternity. DNA can be analyzed from a variety of human samples including blood, semen, saliva, urine, hair, buccal (cheek cells), tissues, or bones. The polymerase chain reaction (PCR) is used to amplify the genomic DNA from a sample and electrophoresis is used to arrange the segment.…

    The advancement of forensic science has progressed immensely since its conception. The contributions it has made for the legal system are immense. One such example are its techniques used to extract DNA during forensic cases. DNA is considered to be one of the most well regarded and highly assessed sources of information (Gershaw et al., 2010). Another important development used during investigations is CODIS or the Combined DNA Index System.…

    Despite all of the good that using science in criminal investigation has done. Like all things there have been some hiccups. DNA testing has both enhanced and eroded the status of forensic science in criminal cases. Conventional forensic disciplines were unable to identify a perpetrator with any true discrimination. For instance, conventional serology (the study antigen or antibodies) field analysis of blood group substances was largely used in sexual assault cases during the 1980s (Mosby's Medical Dictionary 8th edition, 2009).…

    Using DNA to trace people who are suspected of committing a crime has been a major advance in policing. When DNA profiling is used wisely, it can help to convict people who have committed serious crimes or exonerate people who are innocent. However, concerns arise when individuals' tissue samples, computerized DNA profiles, and person data are stored indefinitely on a DNA database. There are concerns that this information could be used in ways that threaten people's individual privacy and rights and that of their families. Policymakers are increasingly coming to grips with legal issues related to taking DNA samples from people who have not been convicted of crimes.…

    When a crime is committed the majority of the time the offender leaves behind biological evidence such as saliva, bodily fluids, hair follicles, and fingerprints. The samples are gathered and tested for genetic clues that ultimately identify or exclude who was present at the time the crime occurred. According to Duncan & Daly-Engel (2006), “Asplen & Friedman indicate ‘recent technological advances have made forensic science extremely important in the criminal justice system.” (p.38) Those advancements are especially helpful to criminal investigation units.…

    What significant role does DNA play in a criminal scene and how has DNA improved in the last forty years? DNA became a standard tool for investigations in 1986 O.J. Simpson case of murder trial. In this crime scene DNA evidence was used to determine who was the killer. The blood at the crime scene clearly stated that O.J. Simpson had been the victim. O.J. Simpson crime was a very popular case and since that crime, forensics started to use DNA fingerprint’s in their investigations.…

    Although there isn't always a definite answer on who did the crime, DNA technology has evolved and is a great tool to provide evidence for a case. With that said, DNA alone is not enough to find a suspect guilty or not guilty. DNA is evidence used to determine who committed the crime, how they committed the crime, or if they are innocent. In 1999, in Australia, a girl was raped, and named Frank Button as the criminal who committed the crime. The sheets and pillowcases from where the assault took place were sent to the laboratory, but not tested.…

    In 1985 Leicester University Geneticist Alec Jeffrey’s developed a technique in which DNA that can identify people by using finger prints also known as DNA Profiling (http://www.sciencemuseum.org.uk/whoami/findoutmore/yourgenes/whydoscientistsstudygenes/whatisdnaprofiling.aspx). Fingerprints are unique to everyone, even identical twins boast different prints so with that in mind fingerprints where a used as a new method of investigating crime scenes. Later new part of the body was found to be unique just like fingerprints, arias like the iris, ears and the DNA code. In this time of age we have the technology to use a methods called STA. All humans are 99.9 percent the same when it comes to our gene code, however scientist look for the polymorphic…

    An imperative aspect in any criminal investigation is obtaining and identifying fingerprints as they are considered one of the most valuable pieces of biological evidence. Fingerprinting is a form of biometrics, which is a science that uses the physical characteristics of individuals in order to identify them (Watson, 2014). Ultimately, fingerprints consist of an arrangement of creases known as fraction ridges and they essentially comprise of pores. These pores are attached to the skins sweat or eccrine glands (Langenburg, 2014). Fingerprints are classified into three different categories which are commonly referred to as either patent, latent or impressed prints.…

    Forensic DNA is the process of using and collecting DNA from crime scenes to solve criminal investigations and to ensure accuracy and fairness in the Criminal Justice System. DNA profiling has grown significantly in the past years and has been extremely useful in identifying suspects, criminals and other people involved in the crime. If the suspect is unidentifiable, DNA evidence is compared to a DNA database to identify the criminal. DNA testing has both advantages and disadvantages many of which relate to ethical, emotional, economic and practicality issues. Research states that an increasing number of criminal investigations have used DNA testing to successfully identify the perpetrator.…
