RNA Polymerase III - 새창 A DNA-dependent RNA polymerase present in bacterial, plant, and animal cells. It functions in the nucleoplasmic structure where it transcribes DNA into RNA. It has specific requirements for cations and salt and has shown an intermediate sensitivity to alpha-amanitin in comparison to RNA polymerase I and II. EC 2.7.7.6.
Synonyms : RNA Polymerase C, C, RNA Polymerase, DNA Dependent RNA Polymerase III, III, RNA Polymerase, Polymerase C, RNA, Polymerase III, RNA
RNA Polymerase Sigma 54 - 새창 A DNA-directed RNA polymerase found in BACTERIA. It is a holoenzyme that consists of multiple subunits including sigma factor 54.
Synonyms : RNA Polymerase SigmaN, RpoN1 Protein, RpoN2 Protein, Sigma54 Protein, Transcription Factor Sigma-54, 54, Sigma Factor, Factor 54, Sigma, SigmaN, RNA Polymerase, Transcription Factor Sigma 54
RNA Precursors - 새창 RNA transcripts of the DNA that are in some unfinished stage of post-transcriptional processing (RNA PROCESSING, POST-TRANSCRIPTIONAL) required for function. RNA precursors may undergo several steps of RNA SPLICING during which the phosphodiester bonds at exon-intron boundaries are cleaved and the introns are excised. Consequently a new bond is formed between the ends of the exons. Resulting mature RNAs can then be used; for example, mature mRNA (RNA, MESSENGER) is used as a template for protein production.

RNA Probes - 새창 RNA, usually prepared by transcription from cloned DNA, which complements a specific mRNA or DNA and is generally used for studies of virus genes, distribution of specific RNA in tissues and cells, integration of viral DNA into genomes, transcription, etc. Whereas DNA PROBES are preferred for use at a more macroscopic level for detection of the presence of DNA/RNA from specific species or subspecies, RNA probes are preferred for genetic studies. Conventional labels for the RNA probe include radioisotope labels 32P and 125I and the chemical label biotin. RNA probes may be further divided by category into plus-sense RNA probes, minus-sense RNA probes, and antisense RNA probes.
Synonyms : Probes, RNA, Probes, RNA Gene, RNA Gene Probes
RNA Processing, Post-Transcriptional - 새창 Post-transcriptional biological modification of messenger, transfer, or ribosomal RNAs or their precursors. It includes cleavage, methylation, thiolation, isopentenylation, pseudouridine formation, conformational changes, and association with ribosomal protein.
Synonyms : Post-Transcriptional RNA Processing, Posttranscriptional RNA Processing, RNA Processing, Post Transcriptional, RNA Processing, Posttranscriptional, Modification, Post-Transcriptional RNA, Modifications, Post-Transcriptional RNA
