What else can I help you with?
What is spindle fibre?
The stuff that comes from the centrioles of a cell that pull apart the chromosomes during mitosis.
What are the jobs of protein fibers during mitosis-?
During mitosis, protein fibers attach to the chromosomes on opposite ends of the cell, then help to pull them apart so that the cell can divide into daughter cells with copies of all the chromosomes.
During which phase of mitosis do the spindle fibers help to pull the chromosomes to the center of the cell where they line up?
During metaphase, the spindle fibers attach to the centromeres of the chromosomes and help pull them to the center of the cell, aligning them along the metaphase plate. This alignment is crucial for ensuring that each daughter cell will receive an equal and accurate distribution of chromosomes during the subsequent phase of mitosis.
What is the name of the fibers that line the chromosomes up at the equator of a cell during mitosis?
Spindle fibers from the centrioles attach to the chromosomes and pull in opposite directions at the metaphesal plate.
What is cellular component helps for the chromosomes apart in mitosis and meiosis?
The cellular component that helps pull chromosomes apart during mitosis and meiosis is the spindle apparatus, which is made up of microtubules. These microtubules extend from the centrosomes (or spindle poles) and attach to the kinetochores of the chromosomes. As the spindle fibers shorten, they exert tension that separates sister chromatids during mitosis and homologous chromosomes during meiosis. This process ensures accurate distribution of genetic material to the daughter cells.
What structures pull the chromosomes apart?
The spindle fibers, which are composed of microtubules, pull the chromosomes apart during cell division. These fibers attach to the centromeres of the chromosomes and help guide them to opposite poles of the cell during mitosis or meiosis.

What is the role of the spindle fibers during mitosis?
They pull the sister chromatids apart.

When during the cell cycle are chromotomes visible?
Chromosomes are visible during cell division, specifically during mitosis and meiosis. This is when the chromosomes condense and become more distinguishable. In interphase, the chromosomes are less condensed and not easily visible as individual structures.

What pulls chromosomes during during mitosis?
During metaphase, the spindles, or microtubules, all start to move to opposite ends. There, they grab the chromatids and pull them back to their opposite sides.
Do the chromosomes separate once in both mitosis and meiosis?
No. In mitosis the chromosomes separate once. In meiosis, in anaphase I, homologous chromosomes separate, but are still attached as sister chromatids. In anaphase II, the sister chromatids separate. So there are two chromosome separations in meiosis.
What is the role of spindle fibers in mitosis?
They pull the sister chromatids apart.
What is a cytoskeletal that pulls chromosomes apart?
The mitotic spindle is a cytoskeletal structure that pulls apart chromosomes during mitosis. It is composed of microtubules that attach to the chromosomes and exert force to ensure accurate separation of genetic material.
