Turnover of retroelements and satellite DNA drives centromere reorganization over short evolutionary timescales in Drosophila

Centromeres reside in rapidly evolving, repeat-rich genomic regions, despite their essential function in chromosome segregation. This study of centromere evolution over short evolutionary timescales in Drosophila reveals dramatic centromere reorganization involving recurrent shifts between retroelements and satellite DNAs.
