<prompt> Non coding RNAs are:siRNAmiRNAtRNAAll  <response>: A, B, C, i.e. siRNA, miRNA, tRNANoncoding nc RNAs are all RNAs that do not encode protein. They are also called non protein coding npc RNA, non-messenger nm RNA, small s RNA, and functional fl RNA. The gene DNA sequence from which a nc-RNA is transcribed as end product is called non coding RNA gene or RNA gene.Non coding nc RNAs include ribosomal r RNA, transfer t RNA, small nuclear sn RNA, small nucleolar sno RNA, sca RNA, small temporal st RNA, micro mi RNA, small interfering siRNAQ, pi RNA, rasi RNA, line RNA, antisense RNA, and long nc RNAs like Xist HOTAIR,Messenger m RNA is a coding RNA.
