Essay On Dna Profiling

Superior Essays
Intro
The technique of DNA profiling was first discovered in 1985 by Sir Alec Jefferys, a Leicester University geneticist. The work that he did in the laboratory led to the discovery of the technique for genetic profiling, which revealed a pioneer method of biological identification. A humans DNA can be found in hair, saliva, blood, and other various human properties. Sir Alec Jeffreys knew that what he had done was going to be revolutionary. After his discovery, he said “My life changed on Monday morning at 9:05 am, September 10th, 1984. What emerged what the world’s first genetic fingerprint” (3). Since it was first discovered in 1985, DNA profiling has had a significant impact on society and has changed forensic science for the better by expanding the amount of information we are capable of obtaining, making it a turning point in history.

Scientific Foundation of DNA Profiling
The DNA (also known as Deoxyribonucleic acid) in cells is formed of two long strands that wrap around each other. There are four different types of bases in DNA, A (adenine), C (cytosine), G (guanine), T (thymine). These bases join together, A with T and U with G, to form a structure that looks like the twisted steps of a

Some people think DNA profiling is great, while others think it is unnecessary. There are pros and cons to DNA profiling. The first pro is that it is not invasive. Getting a sample of DNA is as simple as swabbing a cheek with a sterile cotton swab. Also, DNA profiling reduces the amount of wrongful conditions that occur. No evidence is more concrete than DNA. Additionally, DNA profiling eliminates the possibility of manipulation in paternity tests. Previously, paternity tests were based off of verbal and situational evidence about who the child should be with. No one is capable of manipulating their own DNA to better their chances of winning a paternity case. DNA profiles are very solid

    1. DNA Structure and Function DNA is the type of organic compound that stores the genetic information in a living organism. DNA is made up of two strands of nucleotides, which include a phosphate group, five carbon sugar, and a nitrogenous base. Each individual strand in held together by strong covalent bonds (a bond formed as a result of the distribution of electrons between atoms). The two strands are then joined to each other by hydrogen bonds between complementary bases.…

    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.…

    If you had told someone in the early 1800’s that every cell in your body contains something called DNA made of molecules called nucleotides (DNA) that determine every characteristic about you, from your height and eye color to whether or not you’ll get a certain disease or condition, they would think you were crazy. Today, most students learn about DNA in middle school biology. DNA was first discovered by a German biochemist named Frederich Miescher in 1869, but its importance was not realized until 1953 (DNA). Genetic testing, “a type of medical test that identifies changes in chromosomes, genes, or proteins” (What is Genetic Testing?), however, was first done in the 1910s with ABO blood typing (O’Neil). Today, testing is used for determining paternity, determining a person’s chance of developing or passing on a genetic disorder, and to confirm or rule out a suspected genetic condition (What is genetic testing?).…

    Finally, human error and DNA contamination is a huge concern for ALL free individual’s DNA. Eric Lander in 1990 founded a new center for Genome research at Whitehead, as well as, Massachusetts Institute of Technology (MIT). Eric Lander has been an expert advisor for the defense on many cases. From Lander’s first hand personal experiences as an expert witness on various court cases, he felt compelled to express his observations of the flaws with DNA fingerprinting identification. Lander’s stated, (1989)…

    This work led to the discovery of even more highly variable stuttered regions, termed minisatellites, in which the number of stutters leads to variation. The discovery of both types of variation in DNA led Jeffreys to the accidental discovery of DNA fingerprinting. With this new technique came the ability to distinguish every individual based on variations in the DNA sequence. His work with DNA fingerprinting was used in the investigation of the two murders in Narborough to identify the baker as the culprit. This technique is still used in criminal investigation and Jeffreys continues to explore this topic in his work…

    Prevent Wrongful Convictions in the United States Imagine spending 30 years in jail for doing nothing. It seems impossible, surely the justice system of the United States is better than that. For Lawrence McKinney, it is very possible. McKinney spend 31 years in jail, only receiving a 75 dollar check when he was released, after being proved innocent (Powell). Many more cases just like McKinney’s happen all the time.…

    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).…

    DNA testing is a major flaw in the criminal justice system that can be addressed through upgrading capacity of labs and the amount of DNA the DNA database can store. Imagine being wrongfully convicted for a crime you did not do and spending years behind bars all because the justice system didn't analyze the DNA correctly. This happens to many people every year throughout the country, and there are many problems and causes with DNA identification and there needs to be a solution for it. Wrongful convictions because of DNA is a problem in the justice system. Many cases have not even been tested for DNA.…

    Life Without Sequence On October 5th, 1984, the body of 15-year-old Kristina Hickey was found raped and stabbed behind a mall in Park Forest, Illinois. She had been missing for two days, having last been seen walking on her way home from choir practice. On January 15, 1987, Christopher Abernathy, who was seventeen at the time the murder was committed, was convicted of Hickey’s murder and sentenced to ‘Life’ in prison without the possibility of parole. Abernathy’s sole accuser was a high-school friend who claimed Abernathy had confessed to him, and a suspiciously obtained confession, by Abernathy, to the police.…

    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.…

    The U.S government shouldn’t be allowed to collect and store the DNA of their people for any national security reason and the legislation of any bill should be opposed. One reason is the government will be restricting our privacy if they collect our DNA. The second reason is that the government will want more power and control over the people. The collecting and storing of DNA for any reason shouldn’t be allowed because it is an invasion of privacy.…

    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.…
