What is the role of the spindle fibers during mitosis?
They pull the sister chromatids apart.
What is the role of spindle fibers in mitosis?
They pull the sister chromatids apart.
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.
How is antaphase 2 in meiosis similar to anaphase in mitosis?
The centrioles move apart to opposite ends of the cell, the chromosomes become attached to the fiber connected to centrioles pulling the chromatids apart; when this is over all the chromatids line up.
In which phase do centromeres uncouple sister chromatids are separated and two new chromosomes move to opposite polls of the cell?
This occurs during the anaphase phase of mitosis. In anaphase, the microtubules shorten, pulling apart the sister chromatids at their centromeres. The separated chromatids are then pulled to opposite poles of the cell by the spindle fibers.
What stage do the sister chromatids move to oposite ends of the cell?
SIster chromatids move to opposite poles of the cell when the spindle fibres contract, pulling them apart. This occurs during the stage in mitosis known as anaphase.

What phase of mitosis has cells pulling apart?
The phase of mitosis where cells pull apart is called anaphase. During anaphase, the sister chromatids separate and are pulled towards opposite poles of the cell by the spindle fibers. This ensures that each daughter cell receives an equal and complete set of chromosomes.

What form to help attach and move chromatids to the opposite poles of the cell?
Spindle Fibers
What is the purpose of spindle fibers during mitosis?
Spindle fibers are responsible for separating sister chromatids during mitosis by attaching to the centromere of each chromatid and pulling them toward opposite poles of the cell. This ensures that each daughter cell receives an identical set of chromosomes.
Phase of mitosis which the sister cell begin to separate?
During telophase new nuclear envelopes form around the two groups of daughter chromosomes, the new nucleoli begin to appear, and eventually, as the formation of the two daughter nuclei is completed, the spindle fibers disappear.
What is involved in cell devision in animal cells?
Well the actual process of Mitosis is involved with cell division. Interphase: DNA is replicated. Early Prophase: Nuclear membrane disintegrates. Late Prophase: Chromosomes appear in as double-chromatids. Spindles form. Metaphase: The spindles organise the chromosomes on the equator of the cell. Anaphase: Chromosomes segregate, pulling the chromatids apart. Late Anaphase: Single chromatids are drawn to the centrosomes. Telophase: Two nuclei form. The cell plate forms across the midline of the parent cell. Cytokinesis: Division of cytoplasm is complete. The two daughter cells are separate.
Do chromatids separate during telophase?
Yes, chromatids separate during telophase to form individual chromosomes. This process occurs after the sister chromatids have been pulled to opposite poles of the cell during anaphase by the spindle fibers. The cell then undergoes cytokinesis to complete the cell division process.
