	Non-coding RNA - Wikipedia, the free encyclopedia
		Ribosomal RNA (rRNA) is the primary constituent of ribosomes.
		Ribosomes are the protein-manufacturing organelles of cells and exist in the cytoplasm and attached to the membrane of the endoplasmic reticulum.
		Efference RNA ( eRNA) is derived from intron sequences of genes or from non-coding DNA.

	Nucleolin functions in the first step of ribosomal RNA processing
		Ribosome biogenesis is a complex process which involves the transcription of a large rRNA precursor, its maturation and assembly with ribosomal proteins ( Hadjiolov, 1985 ; Eichler and Craig, 1994).
		A radiolabeled RNA corresponding to nucleotides +541 to +1250 of the mouse rRNA (RNA
		RNA was extracted from the second half of the processing reaction used in Figure 2A and analyzed on a denaturing gel ( Figure 2B).

	Mining Combinations of Structural Motif from SSU 16 S Ribosomal RNA Secondary Structures (Site not responding. Last check: 2007-11-04)
		Ribosomal RNA has been functionally implicated in virtually every aspect of protein synthesis and also provides the structural core for ribosomal assembly and is directly involved in the catalytic process.
		The ribosomal RNA sequences were also widely used as a tool in molecular phylogenetic studies because of their ubiquity, size and low evolutionary rate [4].
		For example, two imaginary RNA sequences, A and B, and drawings of corresponding secondary structures are shown in Figure 1 and the loop sequences separated by stems from 5' to 3' in the primary sequence.

		Ribosomes are the particles that catalyze mRNA-directed protein synthesis in all organisms.
		Many of ribosomal proteins, particularly those of the large subunit, are composed of a globular, surfaced-exposed domain with long finger-like projections that extend into the rRNA core to stabilize its structure.
		Ribosomal protein L11 is one of the proteins from the large ribosomal subunit.

	Re: What is Ribosomal RNA's purpose???
		Ribosomes are the cytoplasmic particles which convert the base codes of all of the cell's mRNA's (the messages transcribed from genes) into protein sequences, to produce all of the proteins in the cell.
		Each ribosome is composed of two parts: a smaller 40S (MW 1,400,000) subunit composed of the 18S rRNA species and 33 proteins; and a larger 60S (MW 2,800,000) subunit composed of three rRNA species - 28S, 5S, and 5.8S - and 49 proteins.
		In fact, recent experiments have shown that there are several cases in which RNA molecules have catalytic activity and can act as enzymes.

		The results in this paper show that the molecular clock of ribosomal RNA from Eukaryotes is uniquely accelerated and highly variable while those of Archaea and Bacteria are not.
