Document Summary
2013 p. 345 before translated to protein, mrna end modified introns removed by rna splicing (enzymes) Rna then transported from nucleus to cytoplasm transcription, translation, can all occur concurrently bacterial mrnas are synthesized solely by the rna polymerase. In prokaryotes: after rna is translated, you still need: Rna splicing: removal of intron sequences capping of 5" end: when 25 nucleotides are processed, cap is added cap is: modified guanine nucleotide cap helps cell distinguish btw mrnas and other rnas in molecule. It carries pre-mrna processing proteins on its tail.
