Abstract:
Noncoding RNAs (ncRNAs) have been found to have roles in a great variety of processes, including transcriptional regulation, chromosome replication, RNA processing and modification, messenger RNA stability and translation, and even protein degradation and translocation. Recent studies indicate that ncRNAs are far more abundant and important than initially imagined. These findings raise several fundamental questions: How many ncRNAs are encoded by a genome? Given the absence of a diagnostic open reading frame, how can these genes be identified? How can all the functions of ncRNAs be elucidated?

Ribosomal RNA Synthesis
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...
