| Abstract: | The structural relationship between the transfer ribonucleic acid (tRNA) and the ribosomal RNA (rRNA) genes of Bacillus subtilis has been studied by restriction endonuclease analysis of total chromosomal deoxyribonucleic acid (DNA) and characterization of DNA fragments cloned in Escherichia coli. The DNA sequences encoding rRNA and tRNA were assayed by hybridization to radioactive RNA. The results support the conclusion that the tRNA genes are interspersed between and closely linked to the rRNA genes of B. subtilis. They probably do not appear between the 16S and 23S rRNA genes as in E. coli. |
