Topoisomerase II may be linked to the reduction of chromosome number in meiosis.
A reduction of chromosome number in meiosis is essential for genome transmission in diploid organisms. Reduction depends on a change in kinetochore configuration.1 A recent study2 connects changes in kinetochores with other changes in chromosome structure and raises the intriguing possibility that topoisomerase II, the DNA untangling enzyme, is involved.
