The impact of DNA in Criminal Justice System Research Paper

The impact of DNA in Criminal Justice System - Research Paper Example The persons who are credited for discovering the DNA of double helix structure are James Watson and Francis Crick. Here, a key point has to be specifically mentioned. It were the endeavors by Linus Pauling, Rosalind Franklin and Maurice Wilkins that were instrumental in ensuring that Crick and Watson faced minimum hassles in coming out with the discovery. (1) (Explore DNA, n.d.) Watson and Crick, who were a biologist and a physicist, respectively, began their efforts in the first part of 1950s. At that point of time Pauling, who was a chemist, identified a key protein structure. Almost during the same period, Wilkins, who also was a physicist, took the initial DNA X-ray pictures. As a matter of fact, it was solely because of these X-ray pictures that everyone got aware that the structure of DNA is helical. (1) (Explore DNA, n.d.) During the early 1950s, Pauling, Crick and Watson had pointed out that the structure of DNA is triple helical, but this theory eventually went on to be disp roved. This error was partly attributable to the fact that Watson misinterpreted a conversation that he had with Franklin. The thing that ultimately made Crick and Watson to go on the right path was the photo-51 of Franklin. As a matter of fact, this particular picture projected the correct pattern of DNA, and based on it, Watson and Crick went on to develop the DNA structure. (1) (Explore DNA, n.d.) Eventually, the basic discovery of DNA was attributed to the efforts of Crick and Watson, and the work of Franklin was not given its due recognition. This can be considered to be rather improper because, as mentioned earlier, it was the photo-51 of Franklin that went on to simplify things for Crick and Watson. Wilkins was working under Franklin, and owing to some sequence of events, she went on to remove him (Wilkins) from the team. Wilkins was very unhappy and he decided to get even with Franklin. Consequently, he befriended both Watson and Crick, and started providing them with key in formation about Franklin’s work. In fact, even the aforementioned photo-51 was the one that Wilkins gave to both of them (Watson and Crick) in a stealthy manner. In light of all the points discussed in this paragraph, it can conveniently be maintained that even Franklin should have been given the credit, with regard to the discovery of DNA. (2) (Heather Kane, n.d.) DNA and criminal justice The scientific procedure that enables in identification of persons based upon sequences of DNA is very precise where; the possibility of error is highly remote, almost non-existent. Owing to that, there have been countless cases where DNA played a key role in both identifying the criminals and also in getting the innocent persons to be acquitted. It would now be very much relevant in focusing on the manner in which DNA is helpful in solving crimes. (3) (National Academy of Sciences, 2011) The gene sequences in a substantial chunk of people are more or less the same. But it has been found th at there are some zones in the sequence of DNA where there are variations from one individual to other. When a comparison of variations in two DNA samples is carried out, it can be known whether or not they pertain to the same person. To elaborate further, when the crime investigation people gather a DNA sample at the scene of the crime, and they also apprehend some suspects, the above analysis of DNA samples is conducted.

Sherman Computer Repair New Direction - Essay Example This research will begin with the statement that business growth and development is characterized by changes in activities and operations of the business, consequently impacting on the performance of the business. Initiating and adopting relevant actions that enhance change realization is a process with risks. These risks are spread across business stakeholders and their impact varies according to the stakeholder being assessed in that regard. Change is inevitable if a business is to remain competitive over time, alongside the need to grow and expand. The degree of change adoption determines what direction the business takes and its competitiveness in the market. High reaction in the market is directly proportional to participation in change by firms. Planning for a new direction in business is essential for any given organization. Sherman Computer Repair cannot refute the fundamental role of planning for new business directions. This is a procedural activity that requires both time and resources to put in place. There are expected outcomes to look forward to prior to the operations and performance of the company. Steps and guidelines should be put in place in order to evaluate and assess the achievements of such a plan over time. It is important to note that organizational change is characterized by barriers that emerge from within and outside the business environment. With that in mind, the internal and external environments of the company should be assessed against the strengths and weaknesses of the company.
