Preferred Label : rna precursors;
MeSH definition : 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.;
