37.Eukaryotic Non-coding RNA transcripts
(A) are functional RNA molecules that don't code for proteins.
(B)play crucial roles in regulating gene expression and other cellular processes.
(C)act as key players in everything from protein synthesis (rRNA, tRNA) to gene silencing (miRNA,siRNA) and complex regulation.
(D)Genes specifying long non-coding RNAs (IncRNAs) оccupy a large fraction of the genomes of complex organisms.
(E)The term 'IncRNAs' encompasses RNA polymerase I (Pol I), Pol II and Pol III transcribed RNAS, and RNAs from processed introns.
