What are chromosomes separated by during mitosis?
the spindle fibers
What phase do centromeres break?
Centromere splitting is something that happens to the Chromosomes during the M Phase (Mitosis) of cell division. During Anaphase (a phase in the M Phase), the centrioles that have sent out spindle fibers and are at opposite poles just tug at the centromere of the Chromosome, causing the centromere to split. Anaphase is basically centromere splitting, where the spindle fibers from the centrioles split the chromosome in half at the centromere.
What is the process that uses spindle fibers to separate the chromatids?
The process that uses spindle fibers to separate chromatids is called anaphase. During anaphase, the spindle fibers pull sister chromatids apart towards opposite poles of the cell, ensuring each daughter cell receives an identical set of chromosomes.
What is the stage that the spindle fibers form?
Meosis is a reductional division, which means the primary cell has to divide twice thus giving four haploid cells. Spindle fibers are formed at Anaphase 1 (of the first division cycle) and Anaphase 2 (of the second division)
WHAT begins with the separation of centromeres?
Anaphase begins with the separation of centromeres. During anaphase, the two sister chromatids, each with its own centromere, are pulled apart towards opposite poles of the cell by the spindle fibers.
Spindle fibers begin to disappear in what phase?
Spindle fibers begin to disappear in the anaphase of mitosis or meiosis. During anaphase, the sister chromatids separate and move towards opposite poles of the cell, leading to the disassembly of the spindle fibers.
What is spindle fibers pull the sister chromatids apart?
During anaphase I of meiosis the spindle fibers pull apart in homologous chromosomes. The spindle fibers are composed of micro-tubules. The spindle fibers continue to shorten during anaphase in order to bring the chromosomes at two poles.During anaphase I of meiosis the spindle fibers pull apart in homologous chromosomes.

What are chromosomes separated by during mitosis?
the spindle fibers
Do centromeres divide at anaphase one or two?
They divide at Anaphase two. In Matephase one the spindle fibers attach to one spindle fiber.
Which phase pulls spindle fibers apart from homologous chromosomes?
Anaphase
What is the structure responsible for the movement of chromosomes during anaphase?
the spindle fibers i think
Do centromeres divide in meiosis anaphase 1 or 2?
at anaphase 2. IN matephase 1 the spindle fiber attach to one spindle fiber. in anaphase 2 they attach to two spindle fibers then divide and move to opposite ends of the cell. now each is an individual chromosone
The two chromatids move toward opposite poles as the spindle fibers attached to them shorten?
Anaphase
What phase in Meiosis do spindle fibers move homologous chromosomes to opposite sides?
Anaphase 1
Spindle fibers disappear when a cell is in what phase of mitosis?
Telophase stage It is the last stage of the five stages. An easy way to remember the steps is I Prefer My Apples Toasted. It stands for interphase, prophase, metaphase, anaphase, and lastly telephase.
What are spindle fibers made from?
Spindle fibers are made from microtubules, which are composed of tubulin protein subunits. These microtubules play a vital role in cell division by helping to separate chromosomes during anaphase.
