What is DNA Profiling - 1659 Words
Forensic Biology and Anthropology Forensic DNA Analysis What is DNA Profiling? There are many different terms used in conjunction to DNA Profiling; DNA testing, DNA typing and genetic fingerprinting. This is a technique which is used by Forensic Scientists by means of assistance in the identification of individuals by their DNA profiles. A DNA profile is an encrypted set of numbers w0hich reflects an individualââ¬â¢s DNA makeup. This encryption can also be used when identifying a person. DNA profiling is NOT however a full genome sequence. (Joseph Wambaugh, 1989) DNA profiles are very useful as although 99.9% of human DNA sequences are the same in every person, there is also enough DNA present which is different; this allows you to be able to distinguish one individual from another. This is the case for everyone apart from monozygotic twins. (Joseph Wambaugh) DNA Profiling exists in blood, bone, hair follicles, saliva, semen, skin and sweat. They are the same in every cell and retain their distinctiveness throughout an individualââ¬â¢s lifetime. Apart from identification, paternity and immigration cases, this technique is also used in medical conditions such as Huntingtonââ¬â¢s disease. DNA profiling involves testing mini-satellites one at a time which then goes on to produce an image which is much simpler than genetic fingerprinting. It provides a pattern which is unique to a particular person and is therefore suitable for forensic purposes. (Turnpenny, P et al 2005).Show MoreRelatedDna Analysis : Dna Profiling725 Words à |à 3 PagesTammy Venhuda Mrs. Paris P.4 English 7-8 10-20-17 DNA Profiling Hook: Have you ever thought about your personal DNA and why it is important to you? Besides showing factors of how you grow, develop, and function, your DNA has more to it. What is DNA profiling? DNA profiling is when someone uses DNA to identify someone, make sure someone is not being wrongly accused, or to claim criminals. But there are pros and cons to DNA profiling. This is because some people are for it and others are againstRead MoreA Brief Look at DNA Profiling1366 Words à |à 6 PagesDNA profiling has several advantages in helping solve crimes, however, there are still disadvantages to this technique. DNA profiling can be beneficial, as well as detrimental to the society we live in. DNA profiling has become the most widely used tool in the field of forensics because of the advantages it has to offer, although there are some drawbacks when it comes to utilizing this technique. DNA profiling has greatly enhanced law enforcement investigation by helping determine the suspect i nRead MoreMaintaining National Dna Database Case Study1120 Words à |à 5 PagesMaintaining National DNA Databases: Struggle between Necessity and Ethic SNEHA SINGH1 1Advocate, Rajasthan High Court, Jaipur, Rajasthan, India Email ââ¬â ssnehassingh1989@gmail.com 1. INTRODUCTION DNA is an acronym, which stands for deoxyribonucleic acid. Every cell in an individualââ¬â¢s body, with the exception of red blood cells and eggs or sperm, contains the full genetic program for that individual in its DNA. The human genome, which consists of about 3 billion base pairs, harbours genetically relevantRead MoreDna Fingerprinting : Fingerprinting And Profiling1219 Words à |à 5 Pagesà à à à à à à à à à à à à DNA Fingerprinting/Profiling à à à DNA fingerprinting and profiling(DNA FP) took over the forensic world in the late 1970s. Since then, profiling has made forensics almost effortless. Profiling has evolved dramatically from the beginning stages of the replications. à à à DNA FP was invented by a man that goes by the name Alec Jeffreys. He was a British geneoligist. This process is called fingerprinting because it is highly unlikely for two people to have is for them to be identicalRead More Against Proposition 69 and the DNA Fingerprint Act Essay1699 Words à |à 7 PagesCaliforniaââ¬â¢s Proposition 69 and the DNA Fingerprint Act both expand criminal DNA databases far beyond what is necessary to protect citizens and prosecute violent crime. DNA profiling techniques and databases have developed largely over the last fifteen years, and the recent expansions are only a part of an ongoing trend of ââ¬Ëfunction creepââ¬â¢ that characterizes database expansion. Proposition 69 and the DNA Fingerprint Act expand DNA databases originally designed to house DNA samples from violent criminalsRead MoreDNA Conviction And The Truth Behind It In the world of forensic science, exoneration holds a very800 Words à |à 4 PagesDNA Conviction And The Truth Behind It In the world of forensic science, exoneration holds a very crucial role. In cases where a person has been convicted of a crime and needs to be proven innocent, exoneration plays a key part. It is what helps the court to decide in a just manner whether the crime was committed by that person or not. Exoneration is based on DNA evidence and therefore, is the most authentic. The main purpose of exoneration is to help the legal system by allowing innocent peopleRead MoreA Visual Of The Mitochondrial Dna1484 Words à |à 6 Pages Figure 2.

Thesis Discussion DNA phenotyping serves to determine the physical attributes of a specific individual based off of genetic material that was left behind at a crime scene. By being able to determine physical traits such as hairRead MoreDn The Hereditary Material1685 Words à |à 7 PagesDeoxyribonucleic acid (DNA) is the hereditary material in humans. It is contained in the nucleus of nearly every cell in the human body and is unique to all individuals except in cases of identical twins. Thus, DNA can be used to identify suspects in forensic casework. DNA can be left behind at forensic crime scenes in a variety of ways. Common sources of human DNA at crime scenes include: saliva, blood, semen, skin, and hair follicles. Saliva samples can provide high-quality and high-quantity DNA, but they doRead MoreDna Profiling And The National Dna Database System1130 Words à |à 5 PagesPart B: Report DNA Profiling: Is it ethical to have national DNA database system? Introduction: Today, the advancing gene technology provides humanity with numerous benefits such as Genetically Modified Food, CRISPER, and one of them is the use of DNA profiling for storing bio-information. DNA fingerprint technology allows mapping of individualââ¬â¢s genetic patterns that can be stored into the database system (What is DNA fingerprint? 2016). The ability to profile gene effectively, DNA fingerprintingRead MoreDna Profiling And The Criminal Justice System1372 Words à |à 6 Pagesto use DNA profiling to match the semen to a suspect. Colin Pitchfork became the first person to be caught based on mass DNA screening, and the first to be convicted based on DNA profiling. The use of Deoxyribonucleic Acid (DNA) in the criminal justice system has greatly tipped the scales in favor of law enforcement, and changed the world that we live in. Court cases that in the past relied heavily on eye witness testimony and circumstantial evidence now have science to back them up. D NA analysis
