Developments of DNA profiles - Essay Example g of the PCR primers are efficient and reliable forensic DNA analysis techniques as there is a inverse correlation between the number of polymorphic loci examined and the probability of identical alleles in two individuals. Developing DNA profiles for the identification of individuals who are unknown or identifiable or victims of accidents, calamities, crimes, and disasters using automated STR multiplex kits that rely on spectral resolution using different colored fluorescent dyes to label the overlapping loci due the presence of alleles that fall in the same size range has proven to be one of the most innovative methods. In fact, the polyacrylamide gels that are used in STR can resolve DNA fragments that differ by as little as 1 nucleotide in length and this precise allele designation eliminates the need for match guidelines and continuous allele distribution models that are usually needed in conventional DNA profiling methods The genes are the smaller portions of the DNA that produce a particular product, such as protein. They are particularly useful in the process for profiling. Other portions of the DNA whose functions are not determined yet are called â€Å"spacer or packer DNA between the genes† (DNA Profiling n.d., p. 2). These areas are called minisatellites while the smaller repetitive sequences are called as microsatellites (e.g. 4 base pairs). Short Tandem Repeats or STRs determine the number of times the sequence is repeated. Though identification is prohibitive in developing countries where the technology is quite expensive due to extensive processing, these countries usually send DNA samples to developed countries for analysis and profiling. (Lehman & Criscuolo 2009, p. 1). The Short Tandem Repeat or STR process of identification is said to be the new methodology is DNA profiling (DNA Profiling n.d., p. 3). The STR loci are said to be the â€Å"informative genetic markers† for DNA profiling currently in use, even for the degraded samples (Budowlea,

Fair Trade Brands - Secrets of the Worldwide Popularity Coursework

Fair Trade Brands - Secrets of the Worldwide Popularity - Coursework Example Fairtrade mainly exists in developing countries and it targets specific areas, for instance, the Handicrafts, Coffee Industry, Tea Industry etc, it does so in order to make sure that the workers and the producers are benefitted and their economic stature improves by participating in Fairtrade. To understand the concept better, its principles should be well understood and they are as follows: â€Å"Creating opportunities for economically disadvantaged producers, Fairtrade is a strategy for poverty alleviation and sustainable development. Its purpose is to create opportunities for producers who have been economically disadvantaged or marginalized by the conventional trading system.† The most important principle of Fairtrade is to ensure that there are ample opportunities provided to the producer, the sole aim of Fairtrade is to ensure the well being of the workers and the producers and in this process the first is to provide opportunities to the producer because only when the producer has opportunities, it can be passed on to the workers. â€Å"Transparency and accountability, Fairtrade involves transparent management and commercial relations to deal fairly and respectfully with trading partners.† Another important principle of Fairtrade is to make sure transparency exists in every activity initiated by it, in the sense that every activity initiated by Fair trade should be without any fusses and problems, fair rules and policies are followed hence ensuring the economic and financial safety of the producer. Another important principle is to make sure that the producer gets complete independence, in the sense that he/she shouldn’t have restrictions hampering their growth, it provides a very good platform for the growth of the producers and it also improves their marketing skills by giving them access to the market where they get to know so many things which they wouldn’t have learned had they not participated in Fairtrade.
