Document Summary

Gene expression: is said to occur when a protein or other gene product is synthesized and is active in the cell. Why is understanding how bacterial cells help regulate gene expression funcdamental issue in biological science: bacteria are the most abundant organisms on earth occupy virtually every habitat known. Questions about bacterial gene expression have enormous practical significance. biologists, are trying to understand which genes are expressed when disase- causing bacteria colonize a person and start an infection) They can respond quickly to dramatic changes in temperature , ph, light, competitors, and nutrients. Changes in gene expression give bacteria the ability to cope with these types of env changes. Bacteria are found on every habitat on earth. Gene expression can be controlled at three levels; translation, transcpriton or post translation (protein activation) Gene expression can be controlled at any step between the synthesis of rna and the activation of the final gene product.
