WebChromosome replication and segregation are key events during the microbial cell cycle that must be completed before a cell divides. To reproduce successfully, every cell must replicate its chromosome (s) and distinguish nascent sister chromosomes from one … WebNov 6, 2024 · Chromosome segregation is carried out by the spindle, a molecular machine built primarily of microtubules. A massive body of evidence in a multitude of model systems, in particular in Xenopus egg extracts, leaves little doubt that microtubules alone are able to assemble the bipolar spindle structure [ 1 ].
