A new study investigates how genetic elements called transposons, or 'jumping genes,' are added into the mix during evolution to assemble new genes through exon shuffling. In the same way that Lego ...

Rearrangements of all sizes in genomes, genes and exons can result from a glitch in DNA copying that occurs when the process stalls at a critical point and then shifts to a different genetic template, ...
