Bacillus subtilis strain PB 2427 temperature sensitive in the synthesis of RNA during spore germination and outgrowth has been characterized to some extent. At non permissive temperature (46 degrees C) strain PB 2427 synthesizes stable and unstable RNA for 50 min from the beginning of germination an

✦ Synopsis
A procedure for the isolation of spontaneous temperature sensitive mutants of Escherichia coli has been developed. They are selected as survivors at high temperature against the combined killing effects exerted by a temperature inducible lambda prophage and either streptomycin plus ampillicin or ampicillin plus cycloserine. The mutants so obtained are blocked in vivo in the synthesis of RNA or protein or both at restrictive temperature.

The ribosomal proteins of temperature-sensitive mutants of Escherichia coli isolated independently after mutagenesis with nitrosoguanidine were analyzed by two-dimensional gel electrophoresis. Out of 400 mutants analyzed, 60 mutants (15%) showed alterations in a total of 22 different ribosomal prote
A simple nonenzymatic procedure is described for the separation of DNA, RNA, and proteins of cultured animal cells. DNA isolated by this procedure is large molecular weight and double stranded.
[C93] is a novel, extranuclear mutant of Neurospora crassa which has a normal mitochondrial phenotype when grown at 25 degrees, but which is deficient in cytochromes b and aa3 when grown at 37 degrees (Pittenger and West 1979). In the present work, the phenotype of [C93] was characterized in greater
