Interspersed within the exons are introns, regions of non-coding DNA. Introns must be removed from the initial transcript of mRNA before the final mature transcript is sent to the ribosome for translation into protein. This removal is done in a coimplex protein structure called the spliceosome.The spliceosome splices out the non-coding introns from the primary mRNA transcript, and stiches the exons back together into the mature mRNA transcript.he spliceosome is a complex of small nuclear RNA (snRNA) and small nuclear protein (snRNP) molecules, snRNAs and snRNPs.
