Yes, something like that. In mitosis, there are 4 stages; Prophase, Metaphase, Anaphase, and Telophase (also remembered as P.M.A.T). In prophase the centrioles start separate and form the spindle fibers and the chromosomes start to separate. In metaphase the chromosomes line up at the equator in the spindle fibers. Anaphase, the spindle fibre pulls half of the chromosomes to each pole, now resulting in 2 sets of identical daughter chromosomes. In telophase the spindle fibers start to disintegrate and a nuclear membrane forms between the two identical daughter chromosomes. In cytokinesis, the cytoplasm starts to separate producing two identical daughter cells.
All in all, the spindle fibers do disappear and TWO (2) new identical daughter cells are formed.
I hope this helps
This occurs during telophase of mitosis.
The phase of mitosis that the nucleus forms is the prophase phase.
The structures that act as the scaffolding for chromosomal attachment and movement are the spindle fibers. These are achromatic filaments that inwardly extend from the poles of a dividing cell.
telophase II No, not Telophase. Took the test, chose prophase, was correct.
I believe that they are formed by the Centrioles in the cell. These centrioles are found inside (encased) in the centrosomes. They combine microtubles and associated proteins (such as Aurora A) to strengthen the spindle fibers.
The role of spindle fibers during cell divsion is that it forms a bridge between the ends of the cell.
The answer is Spindle Fibers.

The Centrosome. It forms Centrioles which form spindle fibers. Some of the spindle fibers attach to the Kinetochore located on the Centromere of chromosomes. The spindle fibers work in conjunction with motor proteins to facilitate disjunction.
