WebSegments of the mRNA that are respliced back together are known as exons (because they exit the nucleus); while the segments of mRNA that are removed from the pre-mRNA are known as introns. The exons (which collectively make up the mature mRNA) leave the nucleus through a nuclear pore and travel to a ribosome in the cytosol and begin the … WebTranscription generates a primary mRNA transcript (pre-mRNA) that contains both exons and introns.
