WebMost importantly nearly ALL mRNA precursors are spliced Splicing is the process by which the non-coding regions, known as introns, are removed, and the coding regions, known as exons, are connected together. Introns were initially thought to be entirely a feature of the eukaryotic genome. WebBoth prokaryotes and eukaryotes process their ribosomal and transfer RNAs. The major difference in RNA processing, however, between prokaryotes and eukaryotes, is in the processing of messenger RNAs. …. The process of removing the introns and rejoining the coding sections or exons, of the mRNA, is called splicing.
