During periods of cellular stress, this structure disrupts its normal activity to form "detention centers" for proteins.
During periods of cellular stress, this structure disrupts its normal activity to form "detention centers" for proteins. This structure is the site of synthesis of signal recognition particles. A set of molecules found in this structure responsible for methylation and pseudoÂ·uridylation are called snoRNAs ["sno"-RNAs]. Barbara McClintock discovered that this structure forms around a namesake organizing region. This structure is composed of a granular component, (*) fibrillar component, and dense fibrillar component. This structure produces a 45S product which is processed into 28S, 18S, and 5.8S RNAs. Coilin links this structure to Cajal bodies. This structure is the location of most rRNA processing since it is responsible for the synthesis and assembly of ribosomes. For 10 points, name this structure found within the nucleus.
