Find below a list of questions some students have put together. I have typed them out for you‚ and I have also modified some of them‚ so I hope you don’t mind. Once you have printed the questions‚ fold the paper in half (lengthways)‚ and cut out the Q & A to test yourself MICROSCOPES AND MAGNIFICATION QUESTIONS AND ANSWERS What does resolution mean? The ability to distinguish between points that are close together What does magnification mean? The extent to which an image has been enlarged

Clostridium Difficile Hemant Sule BIO 2110-Section 303 December 04‚ 2011 Clostridium Difficile is known to be a notorious infection to cause foul smelling diarrhea‚ very well known to almost every healthcare worker. It is one of the most difficult infections to treat in the current healthcare industry‚ and most often related to the use of antibiotics during healthcare treatment. Clostridium Difficile is a spore-forming‚ gram-positive anaerobic toxin-producing bacterium that is a “common”

variicola‚ K. variicola has been identified as one of the causes of bovine mastitis.(10) Klebsiella .spp are often resistant to many antimicrobial agent . Current evidence implicates plasmids as the primary source of the resistance genes.(2)Klebsiella species with the ability to produce extended-spectrum beta-lactamases are resistant to many classes of antibiotics. The most frequent are resistance to aminoglycosides‚ fluoroquinolones

ABSTRACT: Availability‚ low price‚ and high degree of reduction have made glycerol a highly attractive and exploited carbon source for the production of fuels and reduced chemicals. Here we report the quantitative analysis of the fermentative metabolism of glycerol in Escherichia coli through the use of kinetic modeling and metabolic control analysis (MCA) to gain a better understanding of glycerol fermentation and identify key targets for genetic manipulation that could enhance product synthesis

processes. The words recombinant DNA technology‚ DNA cloning‚ molecular cloning‚ and gene cloning all refer to the same process: the transfer of a DNA fragment or interest from one organism to a self-replicating genetic element such as a bacterial plasmid. The DNA of interest can then be developed in a foreign host cell. This technology has been around since the 1970’s‚ and it has become a common practice in molecular biology labs today. “In 1977 scientists at the Asilomar Conference proposed sweeping

Introduction To differentiate between bacteria‚ fungi and yeast‚ we plant four different microbes in plates under the same environment for one week and compare the growth of the four microbes by macroscopic and microscopic observation. Meanwhile‚ the diversity of bacteria and fungi in humans‚ the environment and wood could be observed. In addition‚ the four substrates are cultured in two media‚ MEA and NA‚ under the same condition. Thus‚ how nutrients affect the growth of bacteria and fungi could

manufacture existing medicines relatively easily and cheaply. The first genetically engineered products were medicines designed to treat human diseases. To cite one example‚ in 1978 Genentech developed synthetic humanized insulin by joining its gene with a plasmid vector inserted into the bacterium Escherichia coli. Insulin‚ widely used for the treatment of diabetes‚ was previously extracted from the pancreas of abattoir animals (cattle and/or pigs). The resulting genetically engineered bacterium enabled the
