Definition of Exon Shuffling
Exon shuffling is a phenomenon in molecular biology which helps in the formation of new genes. The new gene is formed when the exons of the same gene are duplicated and are brought together and when two or more than two exons belonging to different genes are joined with each other along with their flanking introns.
Exon shuffling can be brought about by the help of transposons and by the process of crossing over during meiosis. Exon shuffling plays a significant role in the formation and evolution of proteins.
