Over the years, biologists have developed a detailed picture of how dividing eukaryotic cells-cells with a nucleus-copy their chromosomes and parcel identical sets to the resulting pair of cells. Crucial to this dance of chromosomes is the mitotic spindle , an elaborate skeleton of proteins that segregates the threads of DNA appropriately (SN: 8/31/96, p. 140).

An unanswered question is whether bacteria-which, unlike human cells, don't have a nucleus-contain a spindle or som...
