  • Essay On Dna Profiling

    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…

  • DNA Profiling

    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…

  • Pros And Cons Of Dna Profiling

    Today, DNA profiling is well used all over the world. DNA profiling was developed by the geneticist of the Leicester University in 1985. DNA profiling is the process where a specific DNA pattern, called a profile, is obtained from a person or sample of bodily tissue (“DNA profiling Biotech Learning Hub”). By learning DNA profiling, it enable us to identify individuals. It is really common to use DNA profiling now and a lot of people starts to use the technology. While supporters of using DNA…

  • The Pros And Cons Of DNA Profiling

    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.…

  • DNA Profiling In Crime Investigation

    DNA databases store profiles of the DNA of those who have been suspects in investigations or convicted of crimes and are useful in matching samples taken from crime scenes. Many people believe that the DNA databanks are an invasion of privacy because it is such personal, genetic information. People are afraid the DNA could possibly end up misused, while others believe that the databanks are a completely useful and practical source for DNA profiling in crimes. The US would benefit greatly from…

  • DNA Profiling Process Analysis

    DNA profiling is a fast paced technology that allows DNA to be sampled and connected to the identity of one person. One of the main uses for DNA profiling includes finding DNA at crime scenes and having the ability to work out the events that may have occurred (Better Health, 2015). This process includes the collection and sampling of DNA found at the scene of the crime to those who are suspected to have committed a crime. In Australia in 2011, 60% of those held in custody have previously been…

  • Deoxyribonucleic DNA In Forensic Investigation

    Genetic uniqueness is something that stems from natural biological processes as from each generation there are characteristics that are inherited, assorted, reasserted, and combined between people under the bracket of one common denominator: deoxyribonucleic acid (DNA) (US. Congress, Office of Technology Assessment, 1990). In many cases, criminals take the initiative to clean up the crime scenes, which involves fixing furniture, wiping the place for fingerprints or wearing gloves. Additionally,…

  • Gel Electrophoresis Essay

    DNA Gel Electrophoresis Electrophoresis is a process in which macromolecules are separated by utilizing their electrical charge and size. A technique for separating protein molecules of varying sizes in a mixture by moving them through a block of gel, as of agarose or polyacrylamide, by means of an electric field, with smaller molecules moving faster and therefore farther than larger ones. Gel electrophoresis of DNA is used in DNA profiling. When DNA is found at a crime scene, it's sent to a…

  • Dna Evidence

    Crick published a model of the DNA helix in a one page letter to Nature. It began with the now famous understatement: ‘We wish to suggest a structure for the salt of deoxyribose nucleic acid (D.N.A.). This structure has novel features which are of considerable biological interest’” (Laboratory. 2011). This is the very foundation that DNA was discovered. According to Forensic Magazine, “DNA profiling was originally developed as a method of determining paternity, in which samples taken under…

    One thing to note is that I would recommend that new samples be taken from the clothing at each testing stage and not to use the samples tested with LMG as according to a study by Alenazy, Refaat and Babu, 2015 the use of LMG to test samples that then go off for DNA analysis produce poor partial profiles, apparently due to the longevity of the LMG chemiluminescence…
