The process of DNA fingerprinting Essay Example | Topics and Well Written Essays - 750 words

The process of DNA fingerprinting - Essay Example The sides that make up the DNA are twisted around each other in a spirally way. Each turn of the spiral staircase of the DNA is made up of ten rungs. DNA strand is composed of nucleotides that consist of phosphate, deoxyribose sugar and four nitrogen bases (adenine, cytosine, guanine, and thymine). According to Hess and Orthmann (2012, p. 147), â€Å"the linking of the nitrogen bases results to nucleotide sequence which is distinct and different for every person, thereby determining a person’s individual characteristics.† Production of DNA fingerprint involves many diverse steps: the first step of DNA fingerprinting however begins by one obtaining a sample of DNA from materials such as blood, semen or saliva (Bevans 2014). Vaginal fluids, skin, or skeletal remains can also provide samples for DNA fingerprinting. In case of plant, hair roots are good samples. Through employing the current biochemical techniques, one can also multiply the number of DNA present by use of methods such as polymerase chain reaction (PCR). However, some competent researchers have the potential to work with very small samples such as hair root. To access the DNA from the collected samples, some cells are isolated from the sample and then split open. After splitting the cells, the DNA is separated from the cellular debris. The isolated DNA is then treated endonuclease enzymes/ restriction enzymes (specialized enzymes that cut the sugar-phosphate bond of DNA) that cut the DNA at specific sites into small fragments (Reeve 2014). Due to variation of minisatellites composition of different individuals, the DNAs are cleaved at different points resulting to fragments of varying lengths. The different lengths of the DNA fragments are referred to as restriction length polymorphisms (RFLPs). The different sized of the fragments are easily observed by aid of an experiment called Gel Electrophoresis. After cleavage stage, the DNA portions are then introduced to one end of agarose gel (thin

Leadership Essay Example | Topics and Well Written Essays - 1500 words - 19

Leadership - Essay Example It is quite apparent that a great percentage of people do not comprehend the distinction between leadership and management and therefore use the two terms interchangeably. However, the two terms are different since leadership involves motivating and inspiring while management involves administration and control (Northouse 13). Apparently, Leadership is more desirable than management for various reasons. Research has shown that organisations are better off having a few effective leaders and many brilliant managers than the other way around. Many scholars argue that the world needs more leaders than managers. Leadership is more of a trait than an acquired ability. Management can be taught; that is, anybody can be a manager but not everybody can qualify to be a leader. While a manager focuses on attaining results through the application of managerial skills, a leader focuses on improving the quality of performance rather than results. Leadership and management are, however, similar in the sense that they share complimentary attributes. For instance, a good leader should possess good managerial skills and vice-versa. My biggest strength is the ability to think critically and creatively. Critical and creative thinking forms the basis for effective leadership. The ability to analyse situations and develop effective solutions to common problems develops good leadership skills (Hurley and Brown 2). The objective of applying critical and creative thinking is to approach challenges with an open, holistic perspective. For example, if one is performing poorly financially, he /she should trace the root cause of the problem in order to provide a rational solution, free from any biases. Using inductive and deductive reasoning, which are essential to critical thinking, it is possible to create a systematic approach to the problem. The basic

The Free-Trade Area of the Americas Essay Example | Topics and Well Written Essays - 1000 words

The Free-Trade Area of the Americas - Essay Example For the past few years, diplomats from 34 nations have been working hard to push for the establishment of a free trade area. The following are reasons why governments across the Americas are pushing for the free trade area. First, a country will only specialize in selling goods and services which it can do be and trade with other nations for its wants. This is a representation of actual supply and demand of free trade market. This is because when a certain country concentrates the products that it can do best, such a country takes economy of scale advantage and manufactures their products at reduced production costs. Secondly, these governments argue that free trade area will lead to increased imports and exports, thus increasing the availability of products in the involved nations, therefore, bringing healthier competition. Another reason why governments across the Americas are pushing for a free trade area is that it will reduce living costs, thus increasing economic growth. This i s because it will do away with governmental interventions such as taxes and tariffs thus enabling consumers to purchase products at reduced costs. This will also bring good bond between the involved countries leading to healthier governance and diplomatic global ties. Anti-FTAA group claims that free trade agreement extends treaties that were already adopted (NAFTA and FTA) from the acute North of Tierra del Fuego, Canada, and NAFTA had noxious outcomes with Mexico and the impacts negatively workers in the United States and in Canada. Therefore, the protests argue that from this example, it is evident that the FTAA will bring disastrous effects on Latin America. From the protests point of view, the accords of Free Trade are Globalization masterpieces and thus they will allow deregulation as well as the opening of new markets through the elimination of trade barriers such as worker rights and environmental protection. Additionally, these accords will contribute to commodification and privatization of things such as education and healthcare services and due to globalization, Free Trade aims at enriching â€Å"world masters† called big capitalists and financiers.

Is Charter School an Answer for Inner City Students A Study of Dissertation

Is Charter School an Answer for Inner City Students A Study of Inclusion Among Disadvantaged Black Male Students with Disabili - Dissertation Example    Charter schools are public schools in nature and are intended to improve the education system of any nation. They possess a degree of independence in that most of the times they charge little or no tuition and are open to any student who wishes to enroll in them. They are also non sectarian and do not discriminate against any student on the basis of any affiliation be it sex, religion, race or color. They may be funded by the local authority in which it is situated, through the state or federal revenue like other public schools. These charter schools also adhere to state and federal academic standards as a benchmark in their day to day activities.  The basic concept of a charter school therefore, is the exercise of increased autonomy in exchange for accountability to the relevant stakeholders. Charter schools are free to improvise ways of improving the general student performance and achievement through numerous ways. They might do this through offering longer school days or o perating hours. This is what is at times known as remedial classes in some jurisdictions. Here, students spend more hours in class exploring ways of excelling in whatever discipline they are engaged in or are undertaking. This may occur during extended hours during week days, weekends or even during vacations or holidays. The schools may also adjust the curriculum contrary to what is set by the government to provide the learners with more time on the important or core subjects that they need most for their studies. Charter schools may also create a unique school culture whereby a specific school may adopt specific themes such as performing arts, career readiness, classical education, global awareness or meeting the needs of black or autistic students (Betts and Hill, 2010). Recent research has found that inner city kids or under-served students, who attended charter schools in New York City for nine consecutive years, from kindergarten to eighth grade, would close most of the  "Scarsdale-Harlem† achievement gap. The research also found that charter school students in this study won school admission lotteries as compared to other students in other public schools in the state (Reardon, 2009). This is further led credence by a similar study that found that students attending charter high schools in Chicago and Florida had higher ACT scores, graduation rates and college entrance rates than their peers in traditional public schools (Booker, Gill, Zimmer and Sass, 2009) It is therefore true that charter schools are high achiever as they produce positive results in both elementary and middle schools. This therefore means that there should be improved participation of all stakeholders involved in the research about the viability of charter schools. This will require strong and better policy formulation that would eventually lead to high-quality public charter schools. (Betts and Tang, 2008) Inclusion of black male students with disabilities into charter sch ools is understood to mean the integration of the education of male students with disabilities alongside those that are leading a normal life through regular classroom attendance. This is prompted by the urge by different stakeholders such as the

National Economic Policy macroeconomic Essay Example | Topics and Well Written Essays - 1500 words

National Economic Policy macroeconomic - Essay Example This increase in money supply will lead to an increase in output, income and employment. This will be  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   caused by  Ã‚  Ã‚   the fall in interest rate which occurs after the LM curve shifts to the right (Young & Zilberfarb, 2000), as reflected in the IS-LM curve below. It is worth noting that if money supply is increased, while interest rate is held constant, a higher level of income is needed to ensure  Ã‚  Ã‚   that there is a corresponding demand level for money to the supply. This as mentioned earlier moves the LM curve to the right. The increased income and constant  interest rate where the money demand and supply equal each other is seen at the far right of the curve. In case the inflation rate at one point of constant interest rate makes holding money costly, thus few decide to hold it. This calls for rising of income at a certain real interest rate in the universe so as to put the needed money to be held thus maintaining the economic equilibrium , which can be traced to the right of the IS-LM curve (Carlberg, 2000). The components of GDP will be affected as a result of applying this policy. First of all, the aggregate demand will increase. This increase in demand refers to the increase in the number of goods required by consumers in the economy. This is usually a very good thing for triggering an increase in output in the economy. Especially in the short run, this usually raises the production of the economy which is very desirable. This policy will also have a negative effect on employment. One of the reasons for the increased unemployment is the fact that producers react to the high demand by government thus taking production to a higher level. The increase in production demands that  labor increases. The people who are hired earn money thus are able to spend in larger amounts than when unemployed. Question Two   Expansionary fiscal policy A variety of fiscal policies which leads to a rise in government spending, a sh rink in taxes, or a swell in transfer payments is applied to counter the mishaps of economy contraction. The objective of expansionary fiscal policy is to bridge a recessionary gap, ignite the economy, and reduce the unemployment level. Expansionary fiscal policy is sometimes backed by expansionary monetary policy. Taxation Taxation is the major fiscal policy tool that works quickly to correct an ailing economy. Basically individual income taxes levied by the state; however other taxes are also applicable. Taxes are the spontaneous levies that the government charges on the entire the economy to create the proceeds required to provide basic goods and services and to facilitate other state functions. Personal income levies are precisely the taxes gotten from the earnings received by individuals in each house hold. Expansionary fiscal policy works by either a decline of the income tax levies or an instant rebate of levies previously collected. The decrease in taxes empowers the each ho usehold with extra per capita earnings that can be utilized for spending costs, which then ignites cumulative production and employment and translates

Adults Essay Example | Topics and Well Written Essays - 1000 words

Adults - Essay Example He says that aphasia is a disorder that results from damage of parts of the brain that are coordinating language. He further adds that it affects both the young children and adults but emphasizes that it is very common among the older adults. The SLP tells me that aphasia is caused by the damage of the dominant part of the brain that controls most aspects of language. He says that the part of brain that is damaged by aphasia is the left hemisphere. After the brief explanation from the SLP, I went further to interview him about Sarah whom he met earlier having aphasia disorder. According to the SLP, Sarah, 29 years old had aphasia disorder. Before doing anything to her, he welcomed her to sit on a chair at his therapy room. The room was private hence there was no interruption from outside. Then, the SLP explains that he tried to create a rapport with Sarah asking her three general questions about her home, the current activities and her wellbeing. First, the speech-language pathologists established an ongoing relationship with Sarah and her family to provide security and reassurance through good rapport and trust. He adds that Sarah understood and communicated in English very well and that was the language used during their interaction. Just before the SLP could begin his therapy on Sarah, he assured her of the confidentiality of her therapy session and requested her to feel free to respond to his questions regarding her health. The SLP told Sarah that he uses codes in his therapy work to keep the secrets of her work. He also used codes to represent the wo rds expressed by Sarah. In their interaction, the SLP used memos to ensure that the emerging theories supported Sarah’s views about her condition. At the time of coding, the SLP made the memos regarding the relationship between codes. Coding involved the identification of codes using phrases, sentences, and words from their interaction
