National Institute of Justice claims that DNA is "not used to its full potential in the criminal justice system," partly due to the lack of capacity of current laboratories (p. 1). Scores of cases are on hold because of delays and backlogs in testing, even when DNA samples have been collected from crime scenes and suspects. There is also a dire lack of trained personnel who are qualified to analyze the samples, and no concerted effort to improve criminal justice and forensics training in DNA analysis. Budgetary constraints are, on the whole, the root cause of many of the problems hampering efforts to use DNA to its full advantage and ensure a more efficient and effective criminal justice system.
I do believe that DNA testing should ideally be mandatory in cases in which DNA evidence was collected, in order to reduce numbers of wrongful convictions and to positively identify suspects…...

The scientists ran the DNA computer only in a test tube. They foresaw the need for an injectable version for intracellular activities, which could take decades to devise.7
In response to the fear of nonscale robots going around inside the body, the scientists said they placed safeguards into their systems.7 When more reliable DNA computers are invented with fewer mistakes, people could become more comfortable with injectable robots and accept them, the scientists said.7

human DNA sequence composed of a series of letters such as 'accagacagt' and the objective was to decipher this jumble of letters and interpret the results. I suppose I should report that the process went smoothly and that after a bit of research I now consider myself an expert in regard to the new science of DNA Sequencing. However, I have a thousand more questions now than before I began and even the answers I came up with may or may not be correct. I do know for a fact that this is a pretty new art or science and its potential seems limitless. "DNA itself has thus far shown only modest evidence of possessing any intrinsic catalytic activities, although the prospect that more will be discovered in the future is surely plausible."

mlaObviously, enterokinase gene being tied to this chromosome entails a great deal of research interest into the biological functions of the gene and the manner by which it contributes to disease. Defects in PRSS7 therefore are a direct cause of enterokinase deficiency which is a life-threatening intestinal malabsorption disorder. The disorder can be characterized by severe bouts of diarrhea and failure to thrive and thus create a situation of initiating activation of pancreatic proteolytic proenzymes (trypsin, chymotrypsin and carboxypeptidase a).
Animals, like humans, have to handle digestion of exogenous macromolecules without destroying endogenous constituents so the serine protease or enterokinase seems to be a fundamental digestive system requirement. In other words, all vertebrates such as mice or dogs have adapted a two step enzymatic cascade that is used to change pancreatic zymogens over to active enzymes in the lumen of the gut as discovered by researchers in Pavlov's laboratory in the early 1900's. "Extracts of the proximal small intestine were shown strikingly to activate the latent hydrolytic enzymes in pancreatic fluid. Pavlov considered this intestinal factor to be an enzyme that activated other enzymes, or a 'ferment of ferments' and named it enterokinase." (Stone, 2002)

Conclusion
The research showed that DNA evidence can be a valuable tool for the criminal justice system, but the effectiveness of such evidence depends on a number of factors. Among the more salient of these factors was the need to ensure that the DNA sample is collected and stored properly, and that it is transported to a testing facility in a timely and appropriate fashion. Other issues that emerged from the research included the need to maintain a strict chain of custody for all DNA evidence, as well as the need to ensure that the results of DNA testing were interpreted in an informed manner. Finally, the research was consistent in emphasizing that although DNA evidence can help prove innocence and guilt, the accuracy of such evidence depends on the type of DNA testing protocol that is involved and how these results are used in the courtroom.

DNA Cold Case
Using DNA to Solve Cold Cases
Our federal, state and local law enforcement agencies are charged with the responsibility of bringing justice to every case that comes before them. Especially in the case of homicide, the importance of finding resolution through identification and prosecution (where possible) of perpetrators, is a top priority. This is true even as a considerable amount of time lapses since the emergence of a given case. hen an investigation reaches an impasse, exhausts its leads and ultimately finds itself without a trail to follow, it becomes a cold case. Cold cases typically find their way to the backburner as law enforcement agencies focus on solving crimes with more immediately available evidence. It is thus that cases go 'cold,' leaving investigators with no apparent directions to turn for resolution.
However, today, with the emergence and continued refinement in use of DNA evidence, many cold cases are receiving…...

The problems and future of DNA Testing
The scientific soundness of the DNA test has not been doubted at all. Courts have increasingly relied on the outcomes of DNA tests. The common man is at a loss to understand the complexities of the method, and as a result in jury trials it is not taken as standard proof but approached with hesitancy. Jurors are ignorant of science and the 'principles of modern genetics' and can get quite confused by all the jargon and confusing tactics of lawyers who are more interested in their cases rather than scientific truth. ("DNA Fingerprinting and Forensics," 2006) Thus the very process that can throw light on the proceedings and produce unfaultable evidence gets mired in sticky debates. The actual concern about the DNA test is not a confused jury but the process of collecting the data and analyzing it. There is no safeguard…...

Ethical Pros & Cons of Criminal DNA data banks
DNA banking of criminal information is a source of controversy among many human rights activists. According to statistics, Criminal DNA databanks offer an effective means of controlling crime. Genetic information on criminals is being collected and stored in many states as a means of identifying current and future criminals. Statistics support the notion that collecting DNA information on criminals helps reduce crime. Case in point, the Division of Forensic Science has managed an average of 37 "hits" per month, where hits refer to a situation where DNA analysis of a crime scene has resulted in suspect matches from previously convicted offenders and subsequent arrest (DCJS, 2004). In Virginia the DNA databank database contains more than 200,000 of criminals (DCJS, 2004).
Proponents of DNA banks argue that DNA identifying information should be collected on larger segments of the population to better control crime. Currently…...

Huntington's disease (HD) was the first autonomic dominant disorder for which genetic prediction became possible" (Harper, et al., 2000, Journal of Medical Genetics, p. 567). HD is a disease that occurs due to an inherited disorder leading to the death of brain cells. A diagnosis of HD is accomplished through genetic testing which can be implemented at any age regardless of whether the symptoms manifest or not. Although, the specific symptoms vary between people, nevertheless, symptoms can start with people between 35 and 45 years of age and can also start in some individuals at even anearlier age. The disease may affect successive generations if health interventions are not implemented (Mandel, 2016).
Additionally, "the cause of HD is due to a dominant mutation of autosomal form of the gene called Huntington. This shows that a child born by an affected person has a 50% chance of developing or inheriting the disease"…...

Eye Witness Memory and Identification
In the contemporary legal environment, an eyewitness plays a critical role in the legal system. A correct eyewitness identification has helped in advancing an investigation, and can be used to solve a complex case. Despite the importance of eyewitness identification in a legal system, eyewitness misidentification is being identified as the contributing factor to wrongful convictions based on the DNA testing. Typically, the eyewitness misidentification leads to 70% of wrongful convictions based on the DNA evidence in the United States. In cases after cases, it has been proven by the DNA that eyewitnesses are mostly inaccurate. For example, a review of 311 cases reveals that 73% of the convictions have been due to the eyewitness errors leading to wrongful convictions. Evidence have also revealed that eyewitness identifications can sway strong alibis, juries and police. Unfortunately, the memory of some eyewitnesses is either unable to recall events,…...

Decoding the DNA of the Toyota Production System
In the article Decoding the DNA of the Toyota Production System (Spear, Bowen, 1999) (NOTE: this is OK per Harvard citing conventions to put this citation here, after the article) the authors provide a thorough analysis of what differentiates Toyota from other auto manufacturers specifically, and all manufacturers in general terms. The analysis includes key findings with regard to the Toyota Production System (TPS) lean manufacturing best practices including the findings from Black (2007, p. 3663 which states "lean manufacturing calls for redesigning the mass production system" which is exactly what Toyota did in the development of their TPS. Toyota was also able to instill a very strong reliance on the scientific method of learning and instruction as part of the leadership process while also defining an innate ability of this production system to support the foundational elements of…...

Genetic counseling involves the sharing vital information and knowledge by experienced and well trained experts in the field of genetics for individuals with high risks of suffering some genetic disorders or transferring it to their children. It is the responsibility of a genetic counselor to provide relevant information concerning the hereditary nature of certain diseases and their risks of reoccurrence; addresses the concerns of patients, their health care providers and their families; and lends assistance to both the patients suffering these hereditary ailments and their families.
The first genetic counseling center was the Hereditary Clinic established at the University of Michigan in the United States in 1940. Since then, several such centers have been established in different parts of the world.
Through genetic counseling, information is made available to give the needed support to people who are dealing with any genetic disorder or at risk of developing one. When dealing with a…...

Toxicology Testing
History in forensic science is referred to as application of science into law. The process came at a time when crime needed to be solved using sophisticated means, and institutions needed innovations in the field of science. Many techniques were adopted to determine level of toxins in people’s blood or fluids. It has helped identify harmful toxins that would otherwise not have been discovered. Toxicology testing refers to the methods used to determine toxic levels in samples. The process of toxicology testing includes collecting samples, testing the samples by use of special methods like chromatography, analyzing results and finally generating a toxicology report.
The process that leads up to the report is an important aspect for accurate results. This happens to be a highly sensitive area, so maximum cleanliness is required and sterilized materials need to be used. This form of testing is commonly used in police stations and hospital…...
