WebbProphase: Prophase, the first stage of mitosis, involves the recruitment of condensin and the start of the condensation process that lasts until metaphase. The spindle also starts to develop during prophase when the centrosomes shift to their opposing poles and microtubules start to form from the duplicated centrosomes.

Webbför 7 timmar sedan · During meiotic prophase, the essential events of homolog pairing, synapsis, and recombination are coordinated with meiotic progression to promote fidelity and prevent aneuploidy. The conserved AAA+ ATPase PCH-2 coordinates these events to guarantee crossover assurance and accurate chromosome segregation. WebbMitotic 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 …
