Describe the structure and function of the spindle during mitosis?

∙ 13y ago
Spindle fibers are necessary in mitosis as they help in bringing half the number of chromosomes on each side of the cell, so that when the cell divides, the chromosomes are distributed equally in both the daughter nuclei.

∙ 11y agoDuring mitosis, the spindle fibers attach to the kinetochores of the sister chromatids, and move the sister chromatids to the cell equator during metaphase, and then, after the chromatids separate, move the chromosomes to opposite poles during anaphase.

∙ 8y agoAs the centrosomes separate, spindle fibers made of microtubules radiate from the centrosome in preparation for mitosis. This array of spindle fibers is called the mitotic spindle, which serves to equally divide the chromatids between the two offspring cells during cell division. Two types of spindle fibers make up the mitotic spindle: kinetochore fibers and polar fibers.

Structure made of fibers help move chromosomes during mitosis?
Spindle fibers.
Which structure organizes the mitotic spindle during cell division?
the ikterpuschles the microtubules organize spindle fibres during mitosis and meiosis
What is the phase of mitosis if chromosomes attach to the spindle fibers?
Metaphase is when chromosomes attatch to spindle fibers in the phase of mitosis.
Describe how chromosomes are evenly divided during mitosis?
Chromosomes are divided when the spindle fibers drag sister chromatids to opposite ends of the cell.
What is responsible for moving chromosomes during mitosis?
The mitotic/meiotic spindle originating from the centrosomes and composed of microtubule subunits. Kinetochores provide the motive power.Read more: What_structure_is_responsible_for_moving_the_chromosomes_during

Which is an important function of the cell structure in this model?
Correct Answer: C --- They are involved in the separation of chromosomes during cell division.Explanation: Centrioles are involved in microtubule formation. The spindle that draws the chromosomes apart during mitosis is a microtubule structure.
What is used in meiosis but not in mitosis?
Spindle
What anchors the spindle in mitosis?
centriols
When during mitosis do chromosomes attach to spindle fibers?
During mitosis a double-stranded chromosome attaches to a spindle fiber centromere.
What is one major structure that an animal cell shows during mitosis that a plant cell does not show?
Astra rays on both sides of the spindle
