Critical Analysis of a Historical Science Assignment

Critical Analysis of a Historical Science - Assignment Example In DNA data is stored in codes consisting four chemical elements: adenine (A), guanine (G), cytosine(C) and thymine (T) (Watson, 2004). However, we realize that, in human beings, DNA consists of more than a billion elements, which are mostly similar in all humans. The order in which these elements appear determines the availability of elements to build and sustain a being. This can be likened to the order of letters that forms different words and sentences. The four DNA elements combine in a predetermined sequence, that is, A binds with T while C binds with G. This results in the arrangement of elements called base pairs. The ratio of adenine to thymine, and guanine to cytosine govern the pattern of DNA. Further, each element attaches itself to a sugar molecule and phosphate molecule to form a nucleotide. These nucleotides are then aligned in two strands to form a double helix, which is spiral in shape running in an anti-parallel manner. These arrangements are referred to as chromoso mes, which during the process of DNA replication, divide and are copied or replicated to develop more chromosomes. This results in all cells consisting enough chromosomes to support life fully. The key element of DNA is that it is capable of replicating itself to make millions of copies. A DNA strand in a double helix is the prototype for copying the series of bases. This is of paramount importance in cell division as the newly created cells need to obtain a similar DNA trait as the old cell. DNA together with macromolecules such as proteins, lipids and carbohydrates are essential in the establishment and maintenance of any life form, RNA viruses being the exception. The genetic code is the system used in reading the material contained in DNA. The genetic code spells out plan of amino acids which form proteins in the body and is studied by replicating existing DNA strands to RNA acid. This is done through a process referred to as transcription. Beings such as animals, fungi and plan ts, also referred to as eukaryotic organisms gather their DNA in the nucleus, mitochondria or chloroplast of their cells. On the other hand, beings such as bacteria and other single celled organisms commonly referred to as prokaryotes collect their DNA in the cytoplasm. The organization and packing of DNA in cells is tasked upon alkaline based proteins referred to as chromatin. These proteins include histones. Hydrogen bonds between nucleotides help to stabilize DNA; however, we note that interfacing nucleobases in a process referred to as base-stacking is also essential in steadying the DNA helixes. There are two classes of nucleobases, these are: purines which are formed when A and G are combined in the ratio of five to six and pyrimidines formed when six C and T bases combine (Watson, 2004). Biotechnicians examine the characteristics if nuclear based acids through a technology referred to as nucleic acid analogues. These techniques are typically used by medical and biology resear chers. Furthermore, we note that the arrangement of DNA is referred to as sense which is copied to its RNA and, on the other hand, antisense is the term used to refer to the arrangement of DNA on the reverse side. However, it is common for both sense and antisense to appear in a single strand of DNA. RNA antisenses are churned out in prokaryotes and eukaryotes, these RNA antisenses are mandated with controlling gene expression in the process of RNA-RNA base pairing which is quite similar to the base pairing process in DNA

Case study analysis Nike sweatshops and business ehtics

Analysis Nike sweatshops and business ehtics - Case Study Example The sells a number of their products per year but the company lacks a production unit and thus contracts other companies to manufacture for them all around the world. It is estimated that over 900,000 million people are employed in these different companies around the world to produce Nike based products alone. A large number of these companies are based in Asian countries like Philippines, Taiwan, Vietnam, Thailand, Pakistan and Indonesia where critics have accused Nike to offer poor working condition for the workers as opposed to the United States’ labor laws. The company has been accused on several occasions for exploiting the sweatshop labors upon which its operations are based to increase their profitability while exploiting the locals and rewarding them poorly. Nike had total revenue of $16 billion in 2007, a slight improvement from what the company posted in the previous years. Introduction This paper provides a detailed case study of Nike sweat shops as they are curren tly operated and managed across the globe. As part of the analysis, the business model adopted by Nike shall be analyzed in this paper, providing a comparison with other business models that do exist. The core mission, values and visions of the company will also be discussed to ascertain their relevance in the progress of the company. This paper will adopt the five porter analysis technique to describe the strategic plans and approaches adopted by Nike sweatshops. Porter five force analyses is a framework developed to enable consultants conduct critical industry analysis and business strategy development. SWOT analysis of the company will also be conducted to help form a clear basis upon which their success and/or failure will be weighed. Ethical issues in Nike sweatshops have been a major topic both in the United States and in other countries where the company’s goods are manufactured. This case study will also seek to provide a detailed analysis of the ethical conduct and m isconduct of Nike sweatshop to ascertain the relevance of the claims. Finally, recommendations based on the results obtained from the analysis will be provided emphasizing on the legal requirements that guide such recommendations. Existing business model Business model provides an in-depth analysis of the practices of the business that seeks to create, deliver and capture value for the products being handled. In this section, the core operational aspects of the business, strategies employed organizational culture and structure and trading policies will be evaluated. The business model adopted by any organization contributed to a larger percentage its ability to succeed and deliver value to its consumers. Nike has a value proposition that translates into nothing is impossible if you put the right effort and practice into whatever you want to achieve. This has been a marketing strategy adopted by the company for long to enable it retain its sport consumers who require motivation in th eir daily endeavors. The creation of innovation and inspiration to all athletes in the world the company’s core target and this has enabled Nike to maintain its traditional customers in the sporting fraternity (Drago 117). Nike has for long adopted the franchising business model to enable it produce large volumes of products that can meet the demands of its large consumers spread across the world. Franchising is defined as a practice of using other
