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 disproved. 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 information 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 that 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.
