Which structure organizes the mitotic spindle during cell division?
the ikterpuschles the microtubules organize spindle fibres during mitosis and meiosis
Centriole is composed of microtubules and important for organizing the spindle fibers?
Centriole is composed of microtubules and important for organizing the spindle fibers that separates the chromosomes for mitosis or cell division. There are nine types of microtubules.
Where do microtubules attach to chromosomes during mitosis?
kinetochore microtubules bind with spindle fibers.
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
What mitosis is defined as division of what?
Mitosis is division of cells
Which structure organizes the mitotic spindle during cell division?
the ikterpuschles the microtubules organize spindle fibres during mitosis and meiosis
Is cytoskeleton used for division?
Yes. microtubules are part of the cytoskeleton and help separate the DNA during metaphase and anaphase of mitosis. But generally, cytoskeleton is only for cell structure.
What is a mass of fibers or microtubules formed during cell division?
It's called a spindle. Here's the definition, according to The American Heritage Dictionary of the English Language:The spindle-shaped achromatic structure, composed of microtubules, along which the chromosomes are distributed in mitosis and meiosis.
In Mitosis What organelle does the division of the nucleus?
In mitosis, the division of the nucleus is carried out by the spindle fibers. These fibers are formed by the microtubules and are responsible for separating the duplicated chromosomes into two sets in the process called cytokinesis.
Centriole is composed of microtubules and important for organizing the spindle fibers?
Centriole is composed of microtubules and important for organizing the spindle fibers that separates the chromosomes for mitosis or cell division. There are nine types of microtubules.
Are microtubules tubelike proteins?
Microtubules and microfilaments are cellular cytoskeletal networks. Microtubules are tubular proteins made by tubulin polymers. they have role in cell structure, cell movement, mitosis, gene regulation and so on.
What is the function of an aster?
Asters are microtubules(components of the cellular cytoskeleton) produced by centrioles. Their function is to hold the two centrioles in place at the two poles of the cell during cell division(mitosis). Spindle fibres produced by the centrioles are also microtubules which help in organising chromosomes at the equatorial plane of the cell during metaphase. Mitosis in which asters are formed is called astral mitosis.
Where do the spindle fiber come from?
Spindle fibers form a protein structure that divides the genetic material in a cell. The spindle is necessary to equally divide the chromosomes in a parental cell into two daughter cells during both types of nuclear division: mitosis and meiosis.Just before mitosis, the two centrosomes move apart until they are on opposite sides of the nucleus.As mitosis proceeds, microtubules grow out from each centrosome with their plus ends growing toward the metaphase plate. These clusters of microtubules are called spindle fibers.The centrosome was supplied with a mixture of alpha and beta tubulin monomers. These spontaneously assembled into microtubules only in the presence of centrosomes.
What function do perform in animal cell mitosis?
Centrioles are found in animal cells, and they help to organize the assembly of microtubules during cell division. During the interphase stage of mitosis, a pair of centrioles replicates into two pairs of centrioles.
Where do microtubules attach to chromosomes during mitosis?
kinetochore microtubules bind with spindle fibers.
What mitosis is defined as division of what?
Mitosis is division of cells
Why does mitosis have to have microtubules in order to occur?
Mitosis require microtubules because they bind to the chromosomes and pull them to each pole of the cell. The cell can then divide with the respective chromosomes on separate halves of the cell.
