Answer» (a) Prokaryotic transcription (b) RNA polymerase (c) In eukaryotes hnRNA undergo additional processing called as splicing, capping and tailing. In splicing the introns are removed and exons are joined together. In capping methyl guanosine triphosphate is added to the 5-end of hnRNA. In tailing, adenylate residues are added at 3-end in a template.The fully processed hnRNA, called as mRNA, that is transported out of the nucleus for translation. |
