What Anchors the Spindle?

During mitosis, the spindle fibers will bind to a protein complex (known as the kinetochore) at the center of the chromosome. The kinetochore serves as an anchor, allowing the spindle fibers to retract and separate the sister chromatids

sister chromatids
A sister chromatid refers to the identical copies (chromatids) formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. ... The two sister chromatids are separated from each other into two different cells during mitosis or during the second division of meiosis.

What anchors spindle fibers?

the spindle fibers attach to the chromosomes. ... the middle point of the chromosome. centriole. 'anchors' the spindle fibers and assists in pulling apart chromosomes.

What moves chromatids during mitosis?

As mitosis progresses, the microtubules attach to the chromosomes, which have already duplicated their DNA and aligned across the center of the cell. The spindle tubules then shorten and move toward the poles of the cell. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell.
