Discuss the control of transcription in prokaryotic cells Assignment

Discuss the control of transcription in prokaryotic cells - Assignment Example They possess flagella which accounts for the motility of some prokaryotes. These organisms do not contain intracellular membrane bound organelles such as mitochondria and lysosmes. The size of their ribosomes is 70S which is small as compared to that of eukaryotic cells. The most important and distinguishing feature of prokaryotes is regarding their genetic material. They possess both DNA and RNA but their DNA is single stranded. Their genetic material does not lie in a nucleus rather in a nucleoid which does not have a nuclear membrane and consists of DNA which is in a circular form and is loose. The DNA of the prokaryotes is double stranded. This DNA is also not folded and arranged around histones. The prokaryotes do not contain sterols except for one exception which is Mycoplasma Bacterium which contains them. Prokaryotes are organisms which can survive in extreme conditions as for example at temperatures ranging as high as 80 degrees centigrade. The formation of RNA from DNA is termed as transcription. This process is very essential because it is this RNA which then codes for amino acids and hence proteins. The process of transcription is accomplished by an enzyme known as RNA polymerase. The strand of the DNA that is transcribed is in the 3’ to 5’ direction. Hence the transcript that is formed in the opposite direction that is 5’ to 3’ direction. This is because the RNA polymerase functions in the 3’ to 5’ direction on the DNA creating a complementary strand on RNA in which the Adenine always pairs with Uracil whereas the guanine always pairs with the the cytosine. Prokaryotic cells contain only one type of RNA polymerase. This RNA polymerase only is responsible for the formation of all the different types of RNA in the prokaryotes which includes the mRNA, rRNA and tRNA. RNA polymerase has a distinguishing quality that it can initiate the process of

Case study report - Essay Example Demands from the society surpass the educational requirements. The society relies on the services on higher educational institutions to develop future generations of responsible persons. Minus the services of higher educational institutions, the society would be filled with persons with low professional and social portfolios (Brown & Katz, 2009). For this reason, governments have put in place strategies that make the access of the services of higher education much easier. Over the years, the ease of access of higher educational have been made easier. These can be analyzed in terms of the number of higher educational institutions created and the reduced prices of servicing the institutions for educational purposes. In the United Kingdom, the situation is the same. The number of educational institutions in the U.K has increased significantly to cater for the rising demand (Howell, 2012). Additionally, the institutions have made it easier for the public to access the services. Governmen t and educational bodies have also played a major role in creating a more accessible higher education sector. There have been measures in the United Kingdom that have ensured that higher educational institutions quote reasonable prices as fees (Andy, Jon & Robert, 2010). II. Thesis This paper will analyze the major changes, opportunities and difficulties faced by higher education institutions. The paper will also highlight major barriers that limit change in these institutions. Additionally, the paper will provide change management tips that should be embraced by university leaders in order to ensure smooth transitions of changes. For this paper the main focus will be made in regards to the changes experienced by the Higher education Institutions in the United Kingdom. The major change in the U.K. is the mandatory requirement by the institutions to reduce their charges on the tuition fees. III. The case From September, 2012 universities across the United Kingdom are allowed to raise their tuition fees up to ?9,000 annually. This change was protested by many educational bodies and stakeholder but at the gain of higher educational institutions. However, after the creation of these changes challenges started to arise on how this change could be managed. This is because students would aim to go to schools with the cheapest offering. In an argument by Levin (2012) the high demand on education limits the way in which institutions price their tuition fees. The author further points out that tuition fees in the United Kingdom would be fluctuated differently in each institution in order to maintain the competitiveness in the market (Levin, 2012). Additionally, due to the high fees the government will offer bursaries to students. For this reason, institution with the lowest fee quoted will be required to expand to cater for students who could not afford expensive institution. Institutions would also be required to quote cheaper tuition fees in order to capture the atten tion of the government in enabling them to acquire students benefiting from bursaries. Many institutions are now aiming at expanding their institutions by putting place mechanisms that would please both the government and the student population. However, other institution in the United Kingdom remain reluctant to quote cheaper

Teacher Leadership. Behaviors and Importance of Teacher Leaders Essay

Teacher Leadership. Behaviors and Importance of Teacher Leaders - Essay Example Teacher leadership is believed to have played a major role in the act of changes in education. The concept of teacher leadership has played a vital role in changing the professional nature of teachers, changing the reward system of teachers, improvement in the teaching profession with the concept of continuous change and elevating participation of the teachers in the process of making effective decisions. When researchers started researching the notion of teacher leadership, they associated the notion with those teachers who are situated in the formal leadership roles such as teachers working as experienced teachers and teachers working as the department heads (Saha, 2009). Teachers who have assumed these formal position were found to conduct their leadership responsibility outside the class rooms and were given extra time to conduct these responsibilities. Teachers who had assumed formal position as leaders helped other teachers in problem solving and improving school conditions. Te achers assumed these position only with the aim of gaining growth in their professional life or if it was necessary to help their students and classrooms. Teachers who assume these positions do not act as a superior being, they rather work with other teachers as partners or teammates. When teachers assume these leadership positions their roles as teachers increased and these roles enhanced their professional life and teachers started gaining increased say in administrative as well as curriculum aspects of the educational institute. The main point that needs to be taken into consideration is that the effects of this kind of leadership of teachers was obtained because these teachers assumed formal leadership positions in educational institutes and they did not practice leadership roles inside the classroom setting. Researchers have figured out that more positive impact of teacher leadership can be obtained if teachers practice leadership roles within their classrooms (Muijs, 2007). Th e authority structure of schools and educational institutes has been altered in such a way that responsibilities of teachers of these institutes have been increased and these responsibilities promote the notion of teacher leaders within the context of classrooms. Body According to Muijs, the concept of teacher leadership refers to the various behaviors and activities that are together conducted by teachers within an educational institute(Muijs, 2007). This definition of teacher leadership differentiates between the leadership roles played by a teacher within the class and outside the class. The difference is that teacher leaders make use of their relationship with students and colleagues along with curriculum to bring improvement to the educational institute. According to Rinn, the leadership behaviors that are exhibited by the teachers result in enhanced performance of the educational center and the students inside the institute as well as outside the institute but these behaviors are exhibited by teachers within the classroom only(Rinn, 2003). These behaviors are quite informal as compared to the formal behaviors that a teacher exhibits while she is conducting leadership roles outside the classroom. The leadership roles that are conducted outside the classroom are conducted with the aim of enhancing performance of other teachers. The difference between conducting teacher leadership roles within and outside the classrooms does not clearly explain or simplify the notion of teacher leadership. Various activities have been referred to activities conducted by teacher leaders. These activities include: development of the

The comparison of numeracy learning and development Essay

The comparison of numeracy learning and development - Essay Example The paper tells that there is a widespread interest in improving mathematics achievements in schools across the world. Apart from economic benefits of mathematics, such as preparing young men and women for the numeracy requirements of the modern workplaces, and improving the skill levels of the personnel, there are social benefits tied to bettering access for many young people to training opportunities and post school education and laying firm foundations to skills for womb-to-tomb learning. The interest in heightening levels of achievement has resulted in a focus on recognizing the range of factors that determine achievement as well as interpreting how these factors operate to enhance or limit the achievement of varied groups of students. In this case study project, the researcher will consider two students, namely Christopher and John. Christopher has a British background, and he is a gifted learner. He understands the background meaning and culture of a variety of questions. Chris topher is a fast learner, and he always finds a hard time with curriculum demands as well as teachers because they comfortably cater for students with normal learning abilities. John is a Vietnamese who is in England for his studies. He has been in England for five one year and he has a problem with understanding English language, especially in speaking. John does not understand the cultural context of a variety of mathematical questions, and he is in need of constant assistance with understanding key English words. ... ied at the age of 20 years, and his academic studies stopped for about five years, after which he enrolled into a higher learning institution to study Software Security Course. He sired his first child eight years after marriage and, later, after two years, he sired another child. The second child had some mental disability, which called for more care. He took most of his time taking care of his disabled daughter, but he continued with his studies on the part time basis. Christopher decided to enrol on the numeracy level 1 in order to better his numeracy skills because he encountered many calculations including daily purchases. He passed well in level one examination and proceeded to numeracy level two. According to the results of his initial diagnostic test, he had a ‘spiky’ profile. He excellently understood some topics, and at the same time, it was difficult for him to understand other topics regarding numeracy. However, he committed himself to understand the difficul t areas, which resulted to a substantial improvement and success in his level 1 examinations. Now, when he proceeded to numeracy level 2, all topics became equally manageable. It was easier for Christopher to understand every topic because he had gone through the English Education System. His accent and approach enabled him to do well in numeracy because he could ask the lecturer for clarification every time he experienced a problem. When I started to teach in Christopher’s class, Christopher experienced some problems regarding my teaching methods as well as my accent. This was because my approaches were significantly different from the approached that the previous teachers employed in teaching. Therefore, he failed to understand some key concepts concerning numeracy. I did not hesitate to set him
