Chromosome at mitotic metaphase
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. WebThe mitotic phase is a multistep process during which the duplicated chromosomes are aligned, separated, and move into two new, identical daughter cells. The first portion of the mitotic phase is called karyokinesis, or nuclear division.

Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly … In mitosis, the nuclear DNA of the cell condenses into visible chromosomes … A centromere is the central region of a chromosome itself, while the …
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. WebChromosome segregation in meiosis I. At metaphase I, the kinetochores of sister chromatids are either fused or adjacent to one another. Microtubules from the same pole of the spindle therefore attach to the kinetochores …
