Centromere assembly in Drosophila cells.

A cell in the metaphase stage of mitosis is showing recruitment of the centromere-specific protein CID (red) to centromeres (green, alpha-tubulin; blue, DNA). Centromeres are essential chromosomal structures that mediate accurate chromosome segregation during cell division. To ensure faithful inheritance of the centromere locus through cell division, cells must recruit new centromere-binding proteins that would be otherwise diluted at each round of DNA replication. A study from Mellone et al. tracks the cell-cycle timing of centromere assembly in Drosophila melanogaster cells and reports that this organism has evolved a distinct strategy to accomplish this fundamental process.
