The Mechanism of Competence for DNA Uptake and Transformation in Pneumococcihis, concerned mainly with higher plants. The reason for discussing an aspect of bacterial transformation is that in bacteria considerable amount of information is available about the mechanism of DNA uptake in phenomena leading to genetic change and a brief review of this topic in pneumococci could

Integrated and Free State of Plasmidsaining all of the essential genes of the cell. Recently however one has realized that many bacteria in fact contain one or more additional DNA structures usually carrying so called facultative genes that are only essential to the cell’s survival under particular circumstances (e.g. antibioticum resi

The Enzymology of Nitrogen Fixation. It is the step in the nitrogen cycle which compensates for a loss of fixed nitrogen to the atmosphere caused by microbial reduction of the nitrate ion; the complete nitrogen cycle can be represented in many forms such as that below:

The Physiology and Genetics of Nitrogen Fixationnd have permitted rapid advances in the study of the genetics of nitrogen fixation. These developments have stemmed partly from the practical value of the acetylene test and partly from the recognition of the metalloenzyme character of nitrogenase, its extreme oxygen sensitivity and its apparent was
