Rapid centromere evolution: @CecileCourret @AmLarracuente &co's study of #centromere #evolution over short timescales in #Drosophila reveals dramatic #centromere reorganization involving recurrent shifts between retroelements & satellites #PLOSBiology https://plos.io/3CBwHQe

Scientists Unravel Key to the #Centromere’s Eternal Life, Solving Decades-Old Mystery
Researchers discovered that PLK1 triggers a process ensuring centromere preservation during cell division by activating the Mis18 complex and controlling CENP-A loading. This finding is key to understanding how cells correctly divide their genetic material, preventing diseases like cancer.

“Centromeres, the DNA sections often found at the center of the chromosomes, display enormous interspecies diversity, despite having the same vital role during cell division across almost the entire tree of life. An international team of researchers has discovered that the variation in centromere DNA regions can be strikingly large even within a single species.” #dna #isogg #centromere #geneadons https://phys.org/news/2023-05-exploring-centromere-role-formation-species.amp
