They pull the sister chromatids apart.
During metaphase of mitosis, the chromosomes become attached to the spindle fibers.
Spindle fibers are composed of microtubules, which are polymers of the protein tubulin. These microtubules play a crucial role in cell division by helping to separate the chromosomes during mitosis and meiosis.
prophase
Chromosomes attach to spindle fibers during metaphase of mitosis. This is when the chromosomes align at the cell's equator, forming a metaphase plate. The spindle fibers attach to the centromere region of the chromosomes.
The stage of mitosis when spindle fibers attach to the centromeres of sister chromatids is called metaphase.
The cellular component that helps pull apart the chromosome in mitosis and meiosis are the spindle fibers. These spindle fibers are made of micro-tubules.
The fibers that extend from centrosome to centrosome during mitosis are called spindle fibers. They are made up of microtubules and play a key role in the separation of chromosomes during cell division.
Spindle fibers are made of microtubules, which are long, thin protein structures made of tubulin. These fibers play a vital role in the segregation of chromosomes during cell division.
