WebAug 8, 2024 · Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis. During mitosis, the spindle fibers are called the mitotic spindle. WebDec 7, 2024 · What do spindle fibers do in animal cells? These spindle fibers act as guides for the alignment of the chromosomes as they separate later during the process of cell division. Though centrioles play a role in the mitosis of animal cells, plant cells are able to reproduce without them. Why are the centrioles important to the mitotic spindle?
