Metaphase leads to anaphase, during which each chromosome’s sister chromatids separate and move to opposite poles of the cell. More specifically, in the first part of anaphase — sometimes called anaphase A — the kinetochore microtubules shorten and draw the chromosomes toward the spindle poles.Click to see full answer. Regarding this, what organelle moves the chromatids during mitosis?The centriole is an organelle that forms during interphase (growth period) and is that anchor for the spindle fibers and helps shorten the spindle during anaphase to pull apart chromosomes and move them to the opposite ends of the cell.Furthermore, what moves chromatids to each new cell? In particular, two structures called centrosomes move to opposite sides of the cell during this phase and begin building the mitotic spindle. The mitotic spindle plays a critical role during the later phases of mitosis as it orchestrates the movement of sister chromatids to opposite poles of the cell (Figure 2). Also to know, what moves the chromosomes during mitosis? The spindle is a structure made of microtubules, strong fibers that are part of the cell’s “skeleton.” Its job is to organize the chromosomes and move them around during mitosis. The spindle grows between the centrosomes as they move apart.What happens in prophase mitosis?Prophase. The first and longest phase of mitosis is prophase. During prophase, chromatin condenses into chromosomes, and the nuclear envelope, or membrane, breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles (sides) of the cell.
