Verified step by step guidance

Understand the process of mitosis: Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus. It is essential for growth and repair in multicellular organisms.

Identify the stages of mitosis: Mitosis consists of several stages, including prophase, metaphase, anaphase, and telophase. Spindle fibers play a crucial role during these stages, particularly in metaphase and anaphase.

Learn about spindle fibers: Spindle fibers are structures composed of microtubules that form during cell division. They originate from the centrosomes and extend towards the center of the cell.

Explore the function of spindle fibers: During mitosis, spindle fibers attach to the centromeres of chromosomes. This attachment is crucial for aligning the chromosomes at the cell's equatorial plane during metaphase.

Understand the separation of chromosomes: In anaphase, spindle fibers shorten, pulling the sister chromatids apart towards opposite poles of the cell. This ensures that each daughter cell receives an identical set of chromosomes, which is vital for maintaining genetic consistency.
