WebThe embryos were arrested in metaphase at the two-cell stage with high levels of cyclin B1, indicating an essential role of Cdc20 in mitosis that is not redundant with that of Cdh1. Interestingly, Cdc20 and securin double mutant embryos could not maintain the metaphase arrest, suggesting a role of securin in preventing mitotic exit. http://vcbio.science.ru.nl/en/virtuallessons/mitostage/
WebFigure 1: The standard cell cycle. The mitotic phase of the cell cycle (“M” in the diagram above) is comprised of Prophase, Premetaphase, Metaphase, Anaphase and Telophase.

Web27 mei 2024 · The anaphase of meiosis is made up of two consecutive cell divisions, i.e anaphase I and anaphase II. In this stage of meiosis, since there is no DNA replication in between, the diploid cell with two alleles for each gene gets reduced to a haploid cell containing a single allele at each gene. Generally, anaphase I involve separating the ...
