Exon shuffling and the origin of the mitochondrial targeting function in plant cytochrome cl precursor (Long et al., 1995)
An article that illustrates the widespread presence of introns in the eukaryotic genes coding for mitochondrial genes. As well, they show through the existence of conserved introns/exons that the targeting information for the mitochondria has been derived from another protein. This is in line with a gradual evolution of nuclear genes that were targeted to […]
