DNA Fingerprinting
The subject of DNA fingerprinting has become a prominent issue on several fronts. The applicable paradigms involved include law enforcement, privacy concerns and immigration, just to name a few. A few questions and concerns about DNA will be included in this repot including what precisely DNA fingerprinting is, how it is done, the step-by-step methods of fingerprinting, how DNA is compared on an electrophoresis (EPG), what precisely EPG is, whether the author of this report agrees with DNA fingerprinting everyone for medical reasons, why DNA is considered potential evidence in a court of law and whether the author of this report aggress with the government wanting to DNA-fingerprint everyone so that they can learn about disease propensity and other pieces of information. While DNA fingerprinting has and will continue to render a large amount of benefit, the privacy and other rights of people to be fingerprinted are a valid concern.
Analysis
DNA fingerprinting, as many are aware of, is the ability to tie a piece of DNA on a hair, in blood or some other bodily fluid or matter to a person. The most common and well-known applications for DNA is to establish paternity, to tie a person to a crime or crime scene and to screen for diseases and genetic traits such as cancer risk, racial characteristics and so forth. DNA fingerprinting was developed by Alec Jeffreys in 1985. DNA is short for deoxyribonucleic acid. Except with identical twins, everyone's DNA is going to be different as the chances of someone having the same DNA profile is next to zero (Funk & Wagnalls). The three parts to a DNA test is the collection of the sample, the processing of the sample and the interpretation of the results. DNA can be extracted from a range of biological materials such as saliva, blood, semen, hair, muscle tissue, dandruff and even fingerprints (Butler). Evidence must be collected and preserved prior to the testing and it can literally be smaller than what the naked eye can see. The process of analyzing the DNA can take on several forms but there is usually a consistency to it. The material is collected and then process in a centrifuge. There is a transfer to another tube and then there is another centrifuge treatment. After all of this, the PCR DNA test is then performed (Butler). PCR DNA collection and analysis has been both standard and digital, both now and in the past (Dietrich). Gel electrophoresis, commonly referred to as EPG, is used to facilitate DNA separation so that it can be analyzed (Ghanim et al.). EPG is specifically designed as a way to separate DNA, RNA and proteins at the molecular level (Ai).
The government requiring DNA profiles for people across the nation may sound good on its face but it brings up a lot of privacy and other concerns. Many hold that their body is their own (Kaye). This can change quite easily if someone is under criminal or similar suspicion. However, there is also the prospect of DNA being "harvested" via surreptitious means (Scherr). The same thing can happen if the paternity of a child is in question and the prospective father refuses to voluntarily provide a sample. It would be useful to screen for diseases that are present or could be present. It could also be helpful in figuring out why racial disparities exist in terms of why minorities get sick more often than non-minorities (Gorman). The author of this report would not consent to the government asking for it. If the author of this report wants to know the details, the author will go to a private doctor and get (and keep) the information that way. It is not the government's concern and they do not have a "need to know" as the author Is not a criminal or the subject of a paternity/maternity action.
That all being said, DNA is considered evidence in a court of law because it can establish some facts or at least advised assumptions about what happened at a crime scene. It can establish whether there was sexual contact, whether someone was present at a crime scene, whether a potential criminal suffered from wounds rendered by a victim though scratching fingernails or something similar and so on. DNA works as a way to assert or prove all of this because the odds of someone having the same DNA as someone else is so very small that it excludes everyone else except identical twins if they exist. In addition and also as noted before, this is a situation where one's body is not one's own given that the government will issue a warrant or other order to have the DNA collected and analyzed. There are...
DNA Finger Printing Techniques to retrieve DNA and the development of DNA probes have come up and made it possible the matching of DNA molecules to other DNA molecules to serve purposes like identification. This process has been incorporated into what is known as DNA fingerprinting.DNA fingerprinting is therefore a test for identification and evaluation of genetic information i.e. ones DNA. This technique is referred to as a fingerprint because two
DNA The emergence of DNA testing has resulted in the exoneration of many people convicted of crimes. The ACLU (2011) has stated that 17 people on death row were exonerated as of September, 2011. A project in Virginia found 33 individuals convicted of sexual assaults who between 1973-1987 who were still incarcerated in 2012 and whose innocence was demonstrated by DNA testing (Michaels, 2012). DNA testing has proven effective at uncovering

The research paper will cover the usage of DNA as evidence. The importance of DNA in any criminal case as forensic evidence will be discussed through case studies. The role of DNA in court
DNA The Structure and Nature of DNA DNA, or deoxyribonucleic acid, is the basic system upon which life on Earth is constructed. In a very real sense, DNA is a kind of program for life that cells use to replicate themselves and transmit information from generation to generation. Over eons, as life changes and adapts to new environmental conditions, that information is stored in the genetic code of all life on the
DNA Technology in Law and Public Policy The technologies of DNA science have revolutionized modern criminal law in every respect, from crime scene processing and case investigation to prosecutorial strategy and post-conviction appeals. The lightning speed of progress in the DNA sciences represents a public policy challenge to optimize its evidentiary value without violating established principles of constitutional protections, criminal procedure and statutory rules of evidence. Ultimately, projected developments in DNA
All samples must be properly collected, using gloves and other tools in order to prevent contamination, as well as properly stored until analysis can be performed. It is vitally important that this chain of evidence be maintained so that the evidence collected from using the samples can then be admissible in a court of law. This requires those collecting and storing samples not only to use gloves and tools to
