At prometaphase of mitosis?
During prometaphase, the nuclear envelope fragments and the spindle microtubules are able to reach the chromosomes. Each of the two chromatids of each chromosome, at this point, has a kinetochore. The microtubules attach to the kinetochores, forming "kinetochore microtubules" which basically jerk the chromosomes back and forth.
The arrangement of microtubules that become visible during mitosis and that separate the chromosomes into equal groups is called?
these are called spindle fibers. do you hav ms williams? haha
During which phase of mitosis are chromosomes attaching to the spindle?
Chromosomes attach to the mitotic spindle during the metaphase of mitosis. Part of the answer depends on how you define the stages of mitosis and not everybody does this the same way. The short answer is all of them.
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 is the Phase of mitosis in which microtubules connect thecentromere of each chromosome to the poles of spindle?
at the end of prophase
Where do microtubules attach to chromosomes during mitosis?
kinetochore microtubules bind with spindle fibers.
The arrangement of microtubules that become visible during mitosis and that separate the chromosomes into equal groups is called the?
the answer is spindle (or spindle fibers)
The phase of mitosis in which microtubules connect the centromere of each chromosome to the poles of the pindle?
The name for the network of microtubules along which the chromosomes move during cell division is called the spindle fibers. These spindle fibers attach to the chromosomes and pull them in half.
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.
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 organelles are used to move chromosomes?
Microtubules and kinetochore fibers move the chromosomes in mitosis and meiosis, though they are not referred to as organelles. Though you could say that the fibers originate from the centrioles, which are a part of the centrosome.
At prometaphase of mitosis?

The microtubules attach to the kinetochores, forming "kinetochore microtubules" which basically jerk the chromosomes back and forth.
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.
The arrangement of microtubules that become visible during mitosis and that separate the chromosomes into equal is called the?
these are called spindle fibers. do you hav ms williams? haha
What best describes how chromosomes move toward the poles of the spindle during mitosis?
Anaphase(:
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.
What structures are made of hollow protein fibers and are used in the movement of chromosomes during a cell division?
The spindle fibers themselves are composed from microtubules. It is interesting to note that 'motive enzymes' - little enzyme motors - do the actual hauling/moving of the chromosomes along the microtubules from a to b. See MTOC : micro-tubule organizing center.
