SUMMARY
The formation of spindle fibers during prophase is a critical process in mitosis, utilizing tubulin from the cytosolic microtubule network. This network disappears during interphase, allowing for the assembly of the spindle-shaped apparatus that ensures equal chromosome partitioning to daughter cells. Key proteins involved in this process include kinesin-related proteins, which move toward the plus end of microtubules, and dyneins, which move toward the minus end. Understanding these components is essential for comprehending the mechanics of cell division.
