The Histidine Operon of ,cking one of the enzymic activities will grow normally when supplied with exogenous histidine; hence, the pathway has no branch points leading to other metabolites required for growth. About 1500 mutations leading to a requirement for histidine have been described in the cluster of genes specifying

Bacterial Viruses of Genetic Interestetics. Many different bacteriophages have been described; for some of these, such as the T-even phage of ., extensive information is available, while for others, relatively little is known. An attempt has been made to discuss only those bacteriophages for which the genetic analysis is particularly c

Technology Education: History of Research Taxonomy is the branch of biological science involved with identifying, naming, and classifying organisms into a formal hierarchical system. Systematics is the science that deals with the relationships of organisms as approached through their form and function, their genetic systems, their fossil h

This latter aspect has important epidemiological implications for the major pathogenic species, .. Both these characteristics have provided a stimulus for genetic investigations, as well as the need for establishin

This Gram-positive, spore-forming, soil bacillus grows readily in a chemically defined medium and undergoes genetic exchange by transformation and transduction. The simplicity of the cell wall and the morphogenetic events of sporulation have stimulated the development of this
