WebExon shuffling is an essential molecular mechanism for the formation of new genes. Many cases of exon shuffling have been reported in vertebrate genes. These discoveries revealed the importance of exon shuffling in the origin of new genes. However, only a few cases of exon shuffling were reported from plants and invertebrates, which gave rise to … WebIntrons may have helped to accelerate evolution by facilitating recombination between exons of different genes, the process is called exon shuffling.
