Axiomatization of the Nucleolus
Mathematics of Operations Research, 1995An axiomatization of the nucleolus on the set of all cooperative games with finite player set is provided. The nucleolus is shown to be completely characterized by singlevaluedness, anonymity, covariance and a new reduced game property.

To be or not to be in the nucleolus
Nature Cell Biology, 2000Compartmentalization has long been known to have a key role in regulation of cellular processes. By keeping enzymes and regulatory complexes in compartments where the delivery of substrate or exit of product is controlled, competing reactions can occur simultaneously in different parts of the cell.

Annual Review of Cell and Developmental Biology, 1995
The nucleolus is the site within the eukaryotic nucleus of transcription of rDNA, of processing of the rDNA transcripts, and of the formation of pre-ribosomal particles. We review current ideas for the molecular organization of these processes. The earliest transcriptional events take place near the junction of the fibrillar centers and the dense ...

Nucleoli are the sites of biosynthesis of the ribosomal precursors. They contain may copies of the genes for the main rRNAs (18S- and 28 S-rRNA) in the form of tandemly arranged repeats at the chromosomal nucleolar organizer regions (NORs). They also contain the small rRNA (5S-rRNA) that is synthesized outside the nucleolus, specific nucleolar proteins,

Nature Reviews Molecular Cell Biology, 2007
The nucleolus is a distinct subnuclear compartment that was first observed more than 200 years ago. Nucleoli assemble around the tandemly repeated ribosomal DNA gene clusters and 28S, 18S and 5.8S ribosomal RNAs (rRNAs) are transcribed as a single precursor, which is processed and assembled with the 5S rRNA into ribosome subunits.

Critical Reviews in Eukaryotic Gene Expression, 2003
The nucleolus is the most prominent structure within the eukaryotic cell nucleus and is the site where ribosomal RNAs (5.8S, 18S, and 28S) are transcribed, processed, and assembled with ribosomal proteins to form ribosomal subunits. A role in ribosome biogenesis alone, however, does not account for the specific nucleolar localizations of tumor ...

Abstract: The nucleolus represents a highly dynamic nuclear compartment of the interphase nucleus. It plays a key role in ribosome biogenesis. The number of nucleoli, their size, and their activity increase in exponentially growing cells; therefore these parameters reflect the proliferating activity of the cells.

Ribozymes are RNA molecules that behave like enzymes, cleaving other RNA transcripts into pieces. They have potential therapeutic value because they can be designed to chew up viral RNAs or to repair damaged mRNA transcripts. However, getting the ribozyme to the correct part of the cell where the target RNA resides is a challenge.

ABSTRACT The nucleolus, the most prominent feature of the inter-phase nucleus, is involved in ribosome biogenesis (Warner, 1990). During evolution, the nucleolus first appeared at the time when nuclear envelope compartmentation of the cells was taking place. I would like in this review to provide information showing that the nucleolus is
