Cylindrical cytoskeletal structures essential for reorganizing cellular components during division and forming key division machinery. Kinetochore Microtubules
Filaments that attach to centromeres of condensed chromosomes, ensuring accurate chromosome segregation. Chromosomal Microtubules
Filaments connecting to chromosomal ends, distinct from those attaching at centromeres, aiding chromosome movement. Polar Microtubules
Filaments that stabilize other microtubules during division without directly attaching to chromosomes. Astral Microtubules
Filaments radiating from centrosomes toward the cell periphery, helping position division machinery. Centromere
Central chromosomal region where specific microtubules attach, crucial for chromosome alignment and segregation. Mitotic Spindle
Dynamic structure formed by microtubules, responsible for organizing and segregating chromosomes during division. Contractile Ring
Structure at the final stage of division that pinches the cell, physically separating daughter cells. Centrosome
Organelle serving as the main microtubule-organizing center, anchoring astral microtubules during division. Mitosis
Multi-step process where replicated chromosomes are distributed into two daughter cells, driven by microtubule dynamics. Chromosome
Condensed DNA-protein complex that is segregated by microtubule structures during cell division. Motor Proteins
Molecules that facilitate movement and separation of chromosomes along microtubules during division. Interphase
Cell cycle stage preceding division, where microtubules are long and stretched out, preparing for reorganization. Prophase
Early mitosis stage where microtubules begin moving to opposite cell sides, initiating spindle formation. Anaphase
Mitotic stage where chromatids are separated by microtubule action, ensuring equal genetic distribution.
