| Abstract: | The transfer ribonucleic acid (tRNA) populations from log-phase cells, sporulating cells (stage III), and dormant spores were compared by tRNA-deoxyribonucleic acid hybridization techniques. New tRNA species not found in log-phase cells were observed in stage III cells. Some of the tRNA made during sporulation were also present in dormant spores. Although the role and function of these new tRNA species cannot be ascribed directly to the sporulation process, their presence indicates that new tRNA genes can be transcribed during sporulation and suggests that translational control may be exerted during sporulation by tRNA. |
