β¦ Synopsis
Eight hours after infection of KB cells with adenovirus type 12, the rate of conversion from the 325 ribosomal RNA (rRNA) precursor to mature 285 and 5.85 rRNA decreased. An additional RNA species was detected, which appears to be novel, on the basis of its estimated size (about 6.5 kilobases) and its high level of radiolabeling early after infection at low multiplicity.

The ribosomal RNA operons (rrn operons) of Euglena gracilis chloroplasts contain genes for (in order) 16S rRNA, tRNA ne, tRNA Ala, 23S rRNA and 5S rRNA. Major sites of cleavage of the primary rrn transcript were identified by Northern blot hybridization and S 1-mapping. The presumptive termini of al
## Abstract Ribosomal RNA (rRNA) in vertebrates is initially transcribed as a single 47S precursor which is modified by the addition of 2β²βOβmethyl ribose moieties, pseudouridines, and methyl groups, followed by cleavage at several sites to produce the mature 28S, 18S, and 5.8S rRNAs. Cleavage of t
