What Are The Components Of The Mitotic Spindle? The mitotic spindle is a special device essential for chromosome segregation ( mitosis) during cell division. It consists of three parts, chromosomes, two asters and a spindle region (Fig. 1). The overall shape of the mitotic spindle is due to microtubules, which are made of α and
Where Do Spindle Fibers Attach To The Chromosomes? The spindle fibers from the other side of the cell attach to the other sister chromatids of the chromosome. They attach at a point called the kinetochore, which is a disk or protein that is on each side of the centromere. The spindle fibers will move the
On What Structure Of Chromosomes Do Spindle Fibers Attach To? During mitosis, many of the spindle fibers attach to chromosomes at their kinetochores (Figure 6), which are specialized structures in the most constricted regions of the chromosomes. What structure do spindle fibers attach to? Metaphase. During metaphase, spindle fibers attach to the centromere of each
What Forms Spindle Fibers During Mitosis? At the beginning of nuclear division, two wheel-shaped protein structures called centrioles position themselves at opposite ends of the cell forming cell poles. Long protein fibers called microtubules extend from the centrioles in all possible directions, forming what is called a spindle. What produces spindle fibers for mitosis? Microtubules
