Argumentative Essay: What´s DNA Fingerprinting?

Improved Essays
DNA fingerprinting is also known as DNA typing or profiling, and is a method of identifying elements with the base pair sequencing of DNA, which is further used for convicting criminals by profiling an individual’s DNA. This procedure, which enables law enforcement to obtain DNA profiling, first consist of obtaining samples of cells from skin, hair, mucous, and/or blood, all which contain DNA. The DNA is then extracted from the collection, purified, then cut along points that contain proteins; restriction enzymes. The proteins or restriction enzyme pieces are then put through a process called electrophoresis, which separates DNA fragments using gel. Thereafter, the fragments undergo a technique and develop into DNA fingerprinting patterns that can identify individuals that …show more content…
Barnes, was not as advanced as it is today, nor did it have the technology that is now available to us, however, with as many test performed, which included serology, semen swabs, saliva swabs, fingerprinting, and tire imprints, all which were not a match or inconclusive You have to wonder how such a conviction occurred. I believe that the collection procedures at that time were ethical, but like much of the technology used today, and at that time, human error is most at fault for these types of incidences that occur, and those who might of testified should have relayed that information, so that a jury is not left with a negative impressions, and an innocent man would not have gone to prison. Through the years Steven Barnes maintained his innocence, and requested DNA evidence be resubmitted. But it was not until the Innocence Project investigated further, and on their second attempt, was able to overturn the verdict. With the new submission of DNA typing and the advanced technology, Steven Barnes was indeed not the perpetrator of the horrendous crime which he was convicted for, and was exonerated in 2009, based on new test submissions, and the advanced DNA

    The murders of Betty Boyd, Verline Boyd, and Evangela Boyd in 1993 were tragic and heartbreaking. The man accused of the murders, Sherwood Brown, caused the police to chase him and ending up making himself seem even more guilty (Sherwood, 1997). He was convicted of the murders and sentenced to two life sentences and the death penalty. After many attempts made by Brown for DNA testing during his time in prison, the Mississippi Supreme Court granted the testing in 2012 and found he may not be the killer everyone thought him to be (Sherwood, 1997).…

    The first process developed was the Restriction Fragment Length Polymorphisms (RFLP) Method of DNA Profiling. RFLP required large quantities of intact DNA and was really only effective at showing that two samples were different, making its application limited. Short Tandem Repeat (STR) Typing replaced RFLP by making use of the highly unique variable number of tandem repeat sequences in the human genome to differentiate DNA samples. If biological evidence is only found it trace amounts, STR can also use a sample increased by Polymerase Chain Reaction…

    For example, gel electrophoresis is used to solve crimes where a DNA sample of the possible suspects involved are available. The sample can be used to match a suspect to a crime scene. Furthermore, the process lets researchers separate and purify DNA proteins so they can be studied in further detail. In this experiment, we will build a gel electrophoresis, and use it to examine how many components are in varying colors of food coloring dye. The dye that will be examined will represent DNA proteins.…

    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.…

    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.…

    The use of DNA testing in resolving the inconsistencies in the post-conviction cases was particularly useful, as in these cases, the defendant was long requesting and claiming about his erroneous conviction. The technology was extremely useful for examining the biological evidence and proved extremely beneficial in capital cases by identifying the instances of wrongful convictions (Scheck et al., 2000). Then the study by Edward et al. , during the year 1996 study became the pioneer study that could establish the use of DNA testing in finding conclusive evidence for an innocent being wrongfully convicted.…

    DNA Is Junk Essay

    • 4 Pages

    The New York Times article goes into detail about a heated debate of whether or not our Human DNA is junk or not. Although valid points are made from both sides, throughout the article there was a tendency where scientists agreed at some degree that some of the non-coding DNA is junk. Some of the views that the article focuses on are aligned in broad spectra of agreement whether or not most of our DNA is complete garbage. Scientists like Ryan Gregory agreed that complexity of an organism is irrelevant to its genome, because most of DNA (about 98.8 percent) is noncoding DNA, where most of it does nothing for humans but just takes up space. Other scientists refute the idea that noncoding DNA is not important and they alluded to the fact that a lot of noncoding DNA is essential to our survival and development.…

    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.…
