WebMitotic kinetochores are initially captured by dynamic microtubules via a ‘search-and-capture’ mechanism. The microtubule motor, dynein, is critical for kinetochore capture as it has been shown to transport microtubule-attached chromosomes towards the spindle pole during early mitosis. The microtubule-binding Ndc80 complex that is recruited to … WebA cell contains eight chromosomes at the end of prophase I. How many chromosomes will be in each daughter cell at the end of prophase II 4 In metaphase I ________ are aligned along the metaphase plate, and in metaphase II ________ are aligned along the metaphase plate homologous chromosomes; pairs of sister chromatids
Prophase is the first stage of mitosis in animal cells, and the second stage of mitosis in plant cells. At the start of prophase there are two identical copies of each chromosome in the cell due to replication in interphase. These copies are referred to as sister chromatids and are attached by DNA element called the centromere. The main events of prophase are: the condensation of chromosomes, the movement of the centrosomes, the formation of the mitotic spindle, and the b… Webdifferent genes get sorted into gametes independently of one another. In other words, the allele a gamete receives for one gene does not influence the allele received for another …
