5′ Capping and Polyadenylation – Definition, Mechanism
In eukaryotes, transcription and translation occur in the nucleus and cytoplasm, respectively. In prokaryotes, transcription and translation of mRNA occur concurrently. Modifications to mRNA processing are minimal or nonexistent. In contrast, post-synthesis processing of pre-tRNA and pre-rRNA includes cleavage, addition of nucleotides, and chemical modification. Before being transported to the cytoplasm where they are translated … Read more
