Definition
English
:
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.
