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 function of spindle fibers in anaphase?
nothing
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.
During what phase of mitosis do centreomes divide and the chromosomes move toward their respective poles?
During the anaphase stage of mitosis, centromeres divide and the sister chromatids are separated as they are pulled towards opposite poles of the cell by the spindle fibers. This results in the chromosomes moving toward their respective poles.
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 does a spindle apparatus do in mitosis?
Separation of chromatids during anaphase .
What are chromosomes separated by during mitosis?
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 is the structure responsible for the movement of chromosomes during anaphase?

Do centromeres divide at anaphase one or two?
They divide at Anaphase two. In Matephase one the spindle fibers attach to one spindle fiber.
In what phase does the movement of individual chromosomes towards opposite poles occur?
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.
What is the function of spindle fibers in anaphase?
nothing
Which phase of mitosis involves splitting or pulling apart the chromatids?
anaphase
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.
What best describes how chromosomes move toward the poles of the spindle during mitosis?
Chromosomes move toward the poles of the spindle during mitosis by attaching to spindle fibers, which are part of the mitotic spindle apparatus. The spindle fibers shorten, pulling the chromosomes toward opposite poles of the cell, ensuring an equal distribution of genetic material to the daughter cells. This process is essential for accurate cell division and genetic inheritance.
