Abstract

AbstractThe synthesis of poly (A) ‐containing RNA in outgrowing spores of Bacillus subtilis was studied. A significant amount of RNA puls‐labelled with 3H‐uridine is polyadenylated. With the beginning of RNA synthesis in outgrowing spores labelled poly(A)‐containing RNA was detected. The amount of poly(A)‐RNA during the outgrowth and first cell division remains constant. Besides poly(A)‐RNA the synthesis of tRNA and rRNA occurs. These results indicate a simultaneous activation of synthesis of tRNA, rRNA as well as of poly(A)‐contaning RNA during outgrowth of B. subtilis spores.
