During the course of evolution, genomes acquire novel genetic elements as sources of
functional and phenotypic diversity, including new genes that originated in recent evolution …

Complex regions in eukaryotic genomes are typically characterized by duplications of
chromosomal stretches that often include one or more genes repeated in a tandem array or …

Successful completion of spermatogenesis is crucial for the perpetuation of the species. In
Drosophila, spermatid individualization, a process involving changes in mitochondrial …

Concentrative nucleoside transporters (Cnts) are unidirectional carriers that mediate the
