Identify the correct statement w.r.t tailing
(a) Occurs only in the processing of an eukaryotic RNA
(b) Addition of 200-300 adenylate residues at 3’ end
(c) Addition of adenylate residues occur in template independent manner
Splicing, tailing and capping are post transcriptional modifications found only in eukaryotes. In tailing, adenylate residues (200-300) are added at 3'-end in a template independent manner.
