WebA spliceosome locates introns, cuts them out, and then fuses the remaining parts of the mRNA transcript back together. The parts of the mRNA transcript that aren’t spliced out by the spliceosome are called exons. In contrast to introns, exons are the part of an mRNA transcript that actually contain assembly instructions for a protein. WebThe forces shaping intron–exon structures of eukaryotic genes remain among the longest-standing mysteries of molecular biology. Eukaryotic genomes contain from zero to hundreds of thousands of spliceosomal introns ().Given the diverse roles of introns in gene expression and genome stability, from transcription enhancement to transcript …
