∙ 9y agoThe structure that is responsible for moving the chromosomes during mitosis is the spindle fibers. Spindle fibers are microtubules that the chromosomes attach to during cell division. The spindle fibers guide the chromosomes to the poles.

What is the phase of mitosis when the chromosomes stop moving?
Anaphase ends when the chromosomes stop moving.
What does a nucleus do in a mitosis of a single cell?
During the first stage of mitosis, prophase, the nucleus and nucleolus disappear. Mitosis then proceeds into metaphase and anaphase. Then during telophase, the nuclei reappear in the two cells and finally the cells split apart from each other by a process known as cytokinesis.
During which phase of mitosis do the paired chromatids break apart at the centromere to become individual chromosomes before moving toward opposite poles of the cell?
Anaphase!! :)
What structures are made of hollow protein fibers and are used in the movement of chromosomes during a cell division?
The spindle fibers themselves are composed from microtubules. It is interesting to note that 'motive enzymes' - little enzyme motors - do the actual hauling/moving of the chromosomes along the microtubules from a to b. See MTOC : micro-tubule organizing center.
How is anaphase I of meiosis different than anaphase of mitosis?
In anaphase for both types of cell division, the centromeres of each chromosome separates and the spindle fibers pull apart the sister chromosomes. In mitosis, this is the shortest phase of cell division.However, the differences between mitosis and meiosis are different. Because meiosis is when chromosomes are "mixed and matched" in order to make new different combinations, the strands are only mixed up so when they split, they have new genes at their ends. Because mitosis is when chromosomes are duplicated, or cloned, and are copies of each other, when they split, the new cell is the exact same copy as the original.
What is responsible for moving chromsomes during mitosis?
microtubules or cytoskeleton (as in centrioles)
Each individual protein structure that helps to move the chromosomes apart during mitosis is called what?
Name of protein is tubulin which is called spindle fibers when moving chromosomes .
What is the phase of mitosis when the chromosomes stop moving?
Anaphase ends when the chromosomes stop moving.
What plays an important part in mitosis?
The spindle apparatus plays an important part in mitosis. It is responsible for segregating the chromosomes into two daughter cells by attaching to and moving the sister chromatids. This process ensures that each daughter cell receives an equal and complete set of chromosomes.

Anaphase!! :)
When do the chromosomes separate in mitosis?
Sister chromatids separate during Anaphase II of meiosis.*They are pulled apart and then start moving to opposite sides of the cell.
When centromeres divide and chromatids move apart?
The nuclear membrane fades from view
What is the difference between microtubules and filaments?
Microtubules are mainly responsible for cell movement, contraction of the muscles, cyclosis in a plant and moving of amoeboid. While, actin filaments are the ones that transports vesicles, handling chromosomes in mitosis and even has a role in the cell shaping process.

Which phase does the preparation for mitosis occur?
Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. Chromosomes will align, separate, and move into new daughter cells during mitosis. The prefix inter- means between, so interphase takes place between one mitotic (M) phase and the next.
