Science, 1983
The illustration that accompanied the review by C. C. Albritton, Jr., of W. H. Goetzmann and K. Sloan's Looking Far North (Viking, New York, 1982) in the issue of 10 December, page 1109, should have been credited to the Bancroft Library, University of California, Berkeley, as well as to the book under review.

RNA cleavage by small catalytic RNAs
Current Opinion in Structural Biology, 1995Recent studies of the hammerhead ribozyme have provided an insight into its three-dimensional structure. In addition, studies using chemical probes, functional-group modification and mutational analysis, in combination with computer modelling, have led to proposals for the structure of both the hairpin and hepatitis delta virus ribozymes.

Many small RNA species associate with the nucleolar structure. Some of these small nucleolar RNAs (snoRNAs) are required for cleavage processing of ribosomal RNA precursors. There are many pseudouridine residues and methylated riboses in mature ribosomal RNA.

Biochemistry and Cell Biology, 1995
A growing list of small nucleolar RNAs (snoRNAs) has been characterized in eukaryotes. They are transcribed by RNA polymerase II or III; some snoRNAs are encoded in the introns of other genes. The nonintronic polymerase II transcribed snoRNAs receive a trimethylguanosine cap, probably in the nucleus, and move to the nucleolus.

Annual Review of Biochemistry, 1995
The present review summarizes key progress made in characterizing the small nucleolar RNAs (snoRNAs) of eukaryotic cells. Recent studies have shown snoRNA populations to be substantially more complex than anticipated initially. Many newly discovered snoRNAs are synthesized by an intron-processing pathway, which provides a potential mechanism for ...

Disturbances of microRNA generation and functioning as inhibitors of gene expression at the translational level are considered as specific and diagnostic features of cancer. This review also highlights the role of short interfering RNA (siRNA) in modified epigenomic chromatin structure, which may cause cancer transformation. Future directions of cancer

AbstractGenomic imprinting is an epigenetic phenomenon that results in differential expression of both alleles, depending on their parent of origin. We have recently identified many imprinted small non-coding RNA genes belonging to the C/D RNA and microRNA gene families, both of which are usually known to play key roles in post-transcriptional ...

Small Nuclear RNAs and RNA Processing
1983I. Summary Ribosomal RNA, transfer RNA, and messenger RNAs, which comprise about 99% of the cellular RNA, are part of the protein-synthesizing machinery. Many studies in the last 15 years have established the presence of another class of RNA, “small nuclear RNAs” (snRNAs) that account for 0.1-1% of the total cellular RNA.
