Describe the properties and uses of plasmids in G.M. experimentation. Plasmids are extrachromosomal genetic elements found in a variety of bacterial species. They are double stranded; autonomously replicating‚ supercoiled‚ covalently closed circular (ccc) DNA molecules that range in size from 1 kb to greater than 200 kb. Often‚ plasmids contain genes coding for enzymes that‚ under certain circumstances‚ are advantageous to the bacterial host (Table 1). Table 1. Some of the phenotypes conferred

Results Properties of social networks Mean network size was 80.67 (SD = 39.84‚ Mdn = 75)‚ with a range of 10–279 (Figure 1). The shape of the distribution is similar to that found in other studies of social networks (Bernard et al.‚ 1990; Hill & Dunbar‚ 2003). The size of the kin and friend networks is given in Table 1. Multilevel models The results of the two models are presented Table 2. The intraclass correlations (ICCx) of the models were 0.18 for Model 1 and 0.24 for Model 2

Investigating the Properties of pH The manufacture’s claim is that Sensodyne toothpaste micro hardens tooth enamel to help protect against the effects of acid wear‚ helps stop the twinges of pain from sensitive teeth formulated with low abrasivity‚ neutral pH and gentle yet effective cleaning system. To find out if the manufactures claim on Sensodyne toothpaste is the correct level of pH. I expect the Sensodyne toothpaste to be a neutral pH level as the manufactures claim that this products

Paradox 1 states that change occurs overtime at a slow pace because the innovations are usually developed by individuals outside of the school. The top-down

Eggs are a key ingredient used to make a foam. Investigate the functional and chemical properties of eggs and other ingredients when making meringue. Chemical and Functional properties of eggs: Background information Eggs give a smoother texture to microwaveable dishes‚ frozen dishes are better to freeze. The yolk and the egg white cam be used in many different ways for different products of food. Eggs contain a lot of protein and a balance of other nutrition. Some producers require fresh eggs to

Department of Chemistry [Colligative Properties & Osmotic Pressure] Purpose : The experiment this week had two different purposes. The first is to teach us about freezing points. This lab was designed to show us the freezing point of a pure solvent‚ in comparison to a solvent in a solution with a non-volatile solute. The second goal of the experiment is to teach students about osmosis. In the experiment‚ we got to observe osmosis as well as understand dialysis
