Abstract
The hallmark of bacterial survival is its adaptability through the control
of gene expression according to the demands from surroundings. However, it
is being increasingly understood that there are several players in the
process who are acting in spatial and temporal manner all with one goal in
mind, how to keep the organism alive under most difficult situation. At
times they need to survive under limited oxygen or nutrients, or under the
onslaught from free radicals generated as metabolic byproducts. Therefore
several interesting strategies are adopted, many new proteins or small
molecules are synthesized. A large number of them act on RNA polymerase,
the key enzyme in the central dogma of molecular biology. We will discuss
few of these strategies and show how the problems now can also be
addressed at the single molecule level.
