Chromosome at mitotic metaphase
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. WebMetaphase is the second stage of mitosis after prophase and is followed by anaphase. In mitosis, the duplicated genetic material is carried from the nucleus of the parent cell to the two identical daughter cells. During metaphase, chromosomes move to the equator, and this region is known as the metaphase plate.

Recently, it has been shown that telomeres can be elongated during mitosis in these APB-like foci, known as mitotic DNA synthesis (MiDAS) at telomeres (Min et al. 2024b; Özer et al. 2024). However, the molecular mechanism for …
WebJun 9, 2009 · During mitosis in diploid cells, chromosomes replicate and sister chromatids segregate to generate daughter cells that are diploid and genetically identical to the initial cell. During meiosis, two rounds of chromosome segregation follow a single round of replication. At division one, homologous chromosomes recombine and are separated. 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.
