WebJan 4, 2024 · Pre-mRNA splicing is a conserved biological process in which introns within nascent RNA molecules are removed and exons are ligated to form mature mRNA products. 1 Through alternative choices of exons and splice sites during splicing—a process known as alternative splicing—a single gene can produce multiple mRNA … WebMay 8, 2024 · RNA splicing is a form of RNA processing in which a newly made precursor messenger RNA (mRNA) is transformed into a mature RNA by removing the non-coding sequences termed introns. The process of … Evolution of eukaryotes is mediated by sexual recombination of parental genomes and since introns are longer than exons most of the crossovers occur in noncoding regions. In these introns there are large numbers of transposable elements and repeated sequences which promote recombination of nonhomologous genes. In addition it has also been shown that mosaic proteins are composed of mobile domains which have spread to different genes during evolution and whi… brandis group
