Abstract:

Measurements of rRNA and tRNA content of E.Coli Ki2 cells have been made in the following situations a exponential growth in media giving rise to different growth rates b shift up from mineral to rich in amino acids medium c starvation of a relaxed mutant d chloramphenicol treatment e shift down from rich to mineral medium. The conclusions are that 1 the stringent control, which acts during an amino acid starvation, works on both rRNA and tRNA and 2 the control mechanism involved in the regulation of RNA content versus chemical environment works differentially on both species. A mutant with a peculiar behavior during a shift up experiment is described, and a new relaxed mutation is described. Author
