How are cells arrested at metaphase
WebColchicine is the chemical used to arrest cell division at metaphase. Metaphase is that stage of cell division where the chromosomes are arranged on the equatorial plate and they are all condensed ( Not open and decondensed). If you want to visualize chromosomes, you can add colchicine at this stage and arrest cell division. WebThe capacity of Topoisomerase II (Topo II) to remove DNA catenations that arise after replication is essential to ensure faithful chromosome segregation. Topo II activity is monitored during G2 by a specific checkpoint pathway that delays entry into mitosis until the chromosomes are properly decatenated. Recently, we demonstrated that the mitotic …
