WebDuring prophase, the nucleus disappears, spindle fibers form, and DNA condenses into chromosomes ( sister chromatids ). During metaphase, the sister chromatids align along the equator of the cell by attaching their centromeres to the spindle fibers. WebSpindles are microtubule fibers that arrange and move chromosomes. It is necessary to equally divide the chromosomes in a parental cell into two daughter cells during mitosis. Spindle fibers are also called the mitotic spindle. Chromatids, centromeres, kinetochores

WebIn prometaphase, kinetochores appear at the centromeres and mitotic spindle microtubules attach to kinetochores. In metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber. In … WebThe spindle is a stretch receptor with its own motor supply consisting of several intrafusal muscle fibres. The sensory endings of a primary (group Ia) afferent and a secondary (group II) afferent coil around the non-contractile central portions of the intrafusal fibres.

WebDuring metaphase, the mitotic spindle uses the spindle fibers within it and captures the chromosomes. After the chromosomes have been linked to the mitotic spindle by the spindle fibers, the mitotic spindle pulls on these chromosomes and moves them towards the center of the cell into a region referred to as the metaphase plate. WebDuring metaphase one, the tetrads of the cell congregate on the metaphase plate located halfway between the opposing ends of the cell. After this, the spindle fibers attach themselves to the chromosomes by grabbing onto the centromeres of each chromosome.
