WebWe integrate genetic, genomic, and computational approaches to characterize the key steps in mitotic chromosome formation from the G 2 nucleus to metaphase, and we identify roles of specific molecular machines, condensin I and II, in these major conformational transitions. RATIONALE WebThe theory accurately reproduces the experimental contact probability profiles for the mitotic chromosomes in HeLa and DT40 cells. The LE rate is smaller at the start of mitosis and increases as the cells approach metaphase. Condensin II-mediated mean loop size is about six times larger than loops because of condensin I. dws esg equity income tfc
