abstract：:Escherichia coli cells lacking the ribosomal RNA processing enzyme RNase III do no excise the normal RNA precursors p16a (17S) and p23a from nascent rRNA transcripts. These cells produce, instead, slightly larger p16b and p23b precursors. Digestion of p16b or p23b rRNA with RNases A plus T1 yields double-stranded frag...
