WebCytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly after telophase. In animal cells, cytokinesis is contractile, pinching the cell in two like a coin purse with a drawstring. WebQuestion Date: 2024-05-24. Answer 1: Mitosis is used for things like growth and repair. Not all cells divide. Skeletal muscle cells don’t divide. When they are damaged, the missing tissue gets filled in with scar tissue. You might be thinking, “Hey, some people grow their muscles really big!”. That’s true, but they do it by increasing ...
