The centromeres that are replicated from the interphase move away towards the opposite poles of the cell.Tubulins act by incorporating microtubules to the nucleus.At the centromere are microtubules that function by recruiting tubulins.Chromosome condensation forms two sister chromatids which are X-shaped and joined at a point known as a centromere.Topoisomerase specifically topoisomerase 2 helps in the relaxation and unlinking of supercoils formed in interphase, cutting, and releasing of the DNA duplex.Condensins are complex proteins that play a key role in the cell cycle, and majorly the separation of the chromosomes, chromosome condensation, maintaining the structural integrity of chromosomes, and the resolution of DNA topography during intertwining.Chromosome condensation is done by the help of condensins complexes which include condensins and topoisomerase.Condensation forms sturdy, elastic chromosomes to prevent damage and breakage caused by the force of pulling microtubules and cytoplasmic drags experienced during mitosis.Condensation allows structural reorganization to separate the identical sister chromatids, a mechanism known as chromatid resolution.Chromosome condensation is the compacting of the chromatin into well-defined rod-shaped structures known as chromatins.The interphase stage allows DNA replication which uniformly entangles (intertwines) the DNA molecules, for easy separation during mitosis.This is a mechanism that involves the condensing of the DNA that is synthesized during interphase.In animal cells, prophase is the first phase of mitosis and the second phase of mitosis in plant cells.
