In a prometaphase cell
WebMitosis is nuclear division plus cytokinesis, and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase. Interphase is often included in discussions of mitosis, but interphase is technically not part of mitosis, but rather encompasses stages G1, S, and G2 of the cell cycle. Interphase & mitosis WebMitotic cells in prometaphase, however, showed strong localization of both dynein and Ndc80 to kinetochores as expected (Figure 1A, bottom panel; Fig S1A). We then disrupted the function of the Ndc80 complex either by depleting the Hec1 or Nuf2 subunit using siRNA-mediated knockdown or by knocking out the Nuf2 subunit using CRISPR/Cas9-mediated ...

WebOct 4, 2024 · Prometaphase – The stage immediately preceding metaphase, in which the nuclear membrane breaks down. Anaphase – The stage immediately after metaphase, when the chromosomes are separated. Metaphase Plate – The imaginary line in the middle of the cell that chromosomes align on during metaphase. WebThe cell cycle has two major phases: interphase and the mitotic phase ( Figure 6.3 ). During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are …
