Xkid chromokinesin is required for chromosome alignment on the metaphase plate of spindles formed in Xenopus laevis egg extracts. We have investigated the role of Xkid in Xenopus oocyte meiotic ...

Figure 1: Expression of Cdc5 during meiosis. Figure 3: Cdc5 is required to prevent bi-orientation of sister kinetochores at meiosis I. Figure 4: Strains lacking Cdc5 are specifically defective in ...

Cohesion maintenance and chromosome segregation in Drosophila oocytes depend on Sirt1 activity, which declines when prophase ...

During meiosis, paternal and maternal chromosomes duplicate, pair, and exchange parts of their DNA in a process called meiotic recombination. In order to mediate this exchange of genetic material, ...

Mitosis and meiosis are both processes by which cells reproduce, but there are distinct differences between the two. While new cells are generated during mitosis, meiosis is a special type of cell ...

In the process of replicating themselves, cells have another choice: do they want to make an identical copy and be left with two cells? Or do they want to make four “half-copies”, in preparation for ...

During sexual reproduction, haploid gametes (i.e. eggs and sperm) are generated from diploid precursors through the specialized cell division of meiosis. Meiosis reduces ploidy by following one round ...
