the spindle fibers i think
The assembly of microtubules responsible for moving chromosomes during anaphase is called the mitotic spindle. It is composed of microtubules that attach to chromosomes and help separate them into two new daughter cells during cell division.
inhibits the activity of the motor proteins responsible for pulling the chromosomes to opposite poles of the cell, such as kinesin and dynein.
In the context of cell division, chromosomes will aline in the middle of the cell during metaphase, then during anaphase they are pulled apart into two daughter cells by centrioles. I wouldn't say they are ever on opposite poles, also considering that there is no directionality of a cell.
The chromosomes move to opposite poles during anaphase of mitosis or meiosis. This movement is facilitated by microtubules that attach to the centromeres of the chromosomes and pull them apart towards the opposite ends of the cell.
In the process of mitosis, anaphase is the stage when the sister chromatids are pulled apart towards opposite ends of the cell. It is one of the shortest stages of mitosis and is characterized by the rapid movement of the separated chromosomes towards the poles of the cell, preparing for cytokinesis. This movement is facilitated by the action of microtubules and motor proteins.
During anaphase of mitosis, the sister chromatids separate and are pulled to opposite ends of the cell by the spindle fibers. This movement ensures that each daughter cell receives an identical set of chromosomes.
Microtubules and Microfilaments.
The phase of mitosis when the chromosomes stop moving is called metaphase. During metaphase, the chromosomes align at the center of the cell along the metaphase plate before moving to separate poles during anaphase.
anaphase of mitosis. The sister chromatids are separated and pulled towards opposite ends of the cell by the shortening spindle fibers, ensuring that each daughter cell receives a complete set of chromosomes. This movement is crucial for the distribution of genetic material during cell division.
cytoskeleton
During anaphase, the spindle fibres pull the chromosomes apart so that there are two identical sets of chromosomes at opposite ends of the cell. Now, the cell is ready for telophase.
During prometaphase, chromosomes rapidly move towards the mitotic centers in preparation for cell division. This movement is driven by microtubules attaching to kinetochores on the chromosomes, which help to align the chromosomes at the metaphase plate for proper segregation.
