Plasmid analysis - Essay Example The blue plasmid DNA did not contain any of the restriction sites for Hind III or Sac I. Introduction Plasmids are the extra chromosomal DNA molecules which are mostly double –stranded, circular and covalently closed molecules, varying in size from 1 kb to 200 kb. (Sambrook and Russell 2001). They are found in many bacterial species. They replicate independently and use a variety of mechanisms to maintain their copy number. They contain the gene codes for the enzymes that are important for the bacterial hosts. The plasmids act as vectors in the molecular biology experiments. The vectors are the carrier DNA molecules into which the foreign gene of interest is inserted and expressed in the host. This DNA is now called recombinant DNA (Roberts and Murray 1976). This recombinant DNA is able to express the Foreign DNA in the bacteria. These vectors replicate inside the host cell along with the inserted DNA. These vectors are of two types: expression vectors (expression of the clone d gene to give the desired protein) and cloning vectors (produce millions of copies of cloned DNA) (Sambrook and Russell 2001). Restriction endonucleases are the enzymes that cut the DNA at the specific sequences. There are about 200 different restriction enzymes (Siwach and Singh 2007). ... The restriction mapping is used to identify the plasmids. The number of DNA fragments and the size of the DNA fragments depend upon the action of the restriction enzyme (Kruezer and Massey 2008). These DNA fragments thus obtained are separated using the Agarose gel electrophoresis. Restriction mapping consists of three important steps. They are restriction enzyme digestion, agarose gel preparation and sample loading (Kruezer and Massey 2008). Results and Discussion: The nutrient agar plate was inoculated with E.coli, and the antibiotic discs were placed in the four quadrants. Figure1: Antibiotic profile against tetracycline in E. coli DH5alphaE:: pMTL84445 After inoculation at 37 degree Celsius for overnight, it was observed that the antibiotic disc of tetracycline had a clear zone. This indicates that the E.coli culture is resistant to kanamycin, chloramphenicol and ampicillin. There is very little sensitive to tetracycline. Figure 2: Antibiotic resistance profiling: Table 1a : Anti biotic resistance profiling of kanamycin control Kanamycin control E. coli DS941::pRRK Antibiotic disc Zone diameter in mm Chloramphenicol 30 Kanamycin 0 Tetracyline 10 Ampicillin 0 E.coli DS941::pRRK bacteria was found to be very sensitive to Chlormaphenicol and comparatively sensitive for Tetracycline antibiotics. The bacteria showed resistance to kanamycin and Ampicillin.

Energy is the backbone of the manufacturing, transport and commercial industries, such that without efficient energy supply for these sectors, the economy would virtually grind to halt. The UK Energy Generation Industry accounted for 51.8% of the total industrial investment in the United Kingdom in 2010 (DECC, 2013:2). This underlines its major contribution to both the stability and productivity of the economy, not only in its capacity to generate revenues for the economy, but also in supporting the rest of the industries in the economy to maximize their productivity. This report seeks to analyze the structure of the industry, with a view to evaluate the reasons for the structure and the strategic decisions that are influenced by the structure of the industry, as well as the possible future structure of the industry. The other subject of this report will be the analysis of the contribution of the UK energy generation industry to the economy, especially as related to the value added by the industry to the country. Finally, the report will also assess the effects of government sustainability targets on the business plan of Ecotricity, as one of the

Are virtual organisations Multinational Enterprises (MNE) Assignment

Are virtual organisations Multinational Enterprises (MNE) - Assignment Example According to Preston (n.d), there are four key characteristics of virtual organizations as a process. Virtual organisations involve developing relationships with a wide range of partners each having a core competence that complements the others. It capitalises on the ability of telecommunications technology to overcome distance and time related problems. Furthermore, it involves trust between parties. Virtual organisations are also motivated by specific opportunities. As soon as these opportunities are exploited enterprises move on to form new partnerships and alliances. 2.0 Description of MNEs A multinational enterprise (MNE) or corporation (MNC) is an entity that operates in more than one tax jurisdiction whether as a single tax payer entity or as a group of such entities (Fernandez and Pope 2002). MNEs have their headquarters in one country (the parent/home country) and operate subsidiaries in several other countries known as host countries. There are a number of enterprises world wide that operate in this way. MNEs continue to grow and expand their operations because of WTO trade rules which facilitate globalisation as well as the growth of electronic commerce and information technology. Some MNEs have budgets that are larger than some countries and this indicates the extent of their power and influence as it relates to the setting of trade rules and regulations by international bodies. Multinational enterprises have many dimensions to them and can be viewed from several perspectives. These dimensions include and are not limited to management, ownership, strategy and structure. In terms of ownership, it may be argued that an enterprise is multinational if it is owned by nationals of more than one country. Companies that fit this particular criterion include Shell and Unilever which is owned by both British and Dutch interests. Many multinational enterprises do not meet this test as most of them originated in one country. In terms of the management criterion the managers are from different nationalities according to the countries in which they operate. However, as a starting point most multinational enterprises use persons from their home country to lead the management team in the initial stages of their operations in host countries. In terms of strategy, multinational enterprises seek to maximise their profits globally by entering new markets. The structure of these companies is such that the head office which is located in the home country controls the operations of the subsidiaries and assists in the direction and coordination of their activities. According to Moran (2007) MNE investments in the developing world occurs in four distinct forms. They are Foreign Direct Investment (FDI) in extractive industries, FDI in infrastructure, FDI in manufacturing and assembly, and FDI in services. However, multinationals operate in not just developing countries but also developed countries. In addition to FDIs they also provide licenses and mana gement agreements in the fast food and hotel sectors. Therefore, FDI and licensing are the two ways in which MNEs

They encompassed sheep, goats, boars as well as cattle. In the temperate Europe, the commonplace agricultural practices involved cultivation of wheat and oats as well as barley. The populace in this region also hunted animals such as deer, pigs and they also practiced fishing.

Explain your answer and how it corresponds to the law of conservation of mass. (5 points) -The mass would be the same as it started. This is because the law of conservation of mass states that energy cannot be created nor destroyed only changed. One of the reactions you conducted can actually be categorized as TWO different types of reactions. Which reaction is this, and what are the two types of reactions? (5 points) It would be the Magnesium metal and hydrochloric acid solution because it bubbled but it still stayed in its form and didn’t change. It is single replacement or combustion.
