commentary The boundless carbon cycle Tom J. Battin‚ Sebastiaan Luyssaert‚ Louis A. Kaplan‚ Anthony K. Aufdenkampe‚ Andreas Richter and Lars J. Tranvik The terrestrial biosphere is assumed to take up most of the carbon on land. However‚ it is becoming clear that inland waters process large amounts of organic carbon and must be considered in strategies to mitigate climate change. A tmospheric carbon dioxide concentrations increased from ~280 ppm before the industrial revolution to over 384

BIOL 130 Lab Report Identifying Two Macromolecules - Carbohydrates and Proteins 9/26/2013 [Type the company name] INTRODUCTION As the name suggests‚ macromolecules are large molecules that make up more than 90% of the total cell mass. These biological macromolecules vary greatly in size - from several hundred to several hundred million molecular weight units - and are made up of monomer units. There are four major classes of biological macromolecules: proteins‚ carbohydrates‚ lipids

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

Recent Advances on DNA based method in Food Analysis Food Analysis From the introduction of the application of science in the study of food and consumption‚ it has been observed that analysis played a key role in the Food industry. From determining composition to the presence of adulterants‚ food analytical methods are essential in maintaining quality and integrity of food products for consumer use. The Speed and Accuracy of the results are crucial in choosing a method for analysis. Methods

great impact in cancer chemotherapy Cao et al. first found this functional interaction between 53BP1 and BRCA1 by investigating the effect of mutations in other DNA repair and checkpoint proteins on BRCA111/11 mutant cells. 53BP1‚ a nuclear protein‚ is the human ortholog of yeast DNA damage checkpoint proteins Rad9p/Crb2‚ with a key role in DNA repair response and checkpoint control (Cao et al‚ 2009). Upon the induction of DNA DSBs‚ 53BP1 rapidly redistributes from a diffuse nuclear localization
