by the pulling apart movement required to make two new daughter cells. spindle fibers attach to the opposite ends of the poles during metophase which creates the chromosomes to split. this process of splitting is also known as binary fission

The centromere is a region in which?
The centromere is the most condensed and constricted region of a chromosome, to which the spindle fiber is attached during mitosis.
Fiibers extending from cell pole to cell pole are called what?
spindle fiber
Where do microtubules attach to chromosomes during mitosis?
kinetochore microtubules bind with spindle fibers.
What is a function of those spindle microtubules that do not attach to kinetochores?
microtubules attached to a chromosome Wiki Answers respondents need to start answering questions with a greater sense of purpose. People do not ask questions to receive a terse, slightly correct answer. They want a valid answer to a valid question. As per this one, kinetochore microtubules are NOT just microtubules attached to a chromosome. They are microtubules attached to kinetochores on the centromeres of chromatids. Two chromatids make up a "chromosome" and each chromatid has a centromere with a kinetochore on it. When microtubules from the spindle pole attach to the kinetochores on each side of the "chromosome" the two kinetochore microtubules (from opposite poles of the cell) successfully pull the "chromosome" apart and provide each new developing daughter cell nucleus with a chromatid from that chromatid pair.
What are spindle fibers made of?
Spindle fiber is made of clusters of aggregated microtubules. The spindle fibers will form at opposite poles of a cell during the prophase in mitosis.
The chromatid is attached to a spindle fiber by what?
one word Centromere
What attaches the spindle fiber to the chromatid?
the kinetochore
During metaphase the centrometers attach to what structures?
In animal cells, during metaphase stage of the cell cycle, the centrioles attach to spindle fibers. These spindle fibers are also attached to the chromosomes which are now aligned at the metaphase plate.
The centromere is a region in which?
The centromere is the most condensed and constricted region of a chromosome, to which the spindle fiber is attached during mitosis.
Two chromatids of a chromosome are attached at a point called?
The two chromatids of a chromosome are attached at a point called the centromere. It is the point which it is attached to a spindle fiber during the process of cell division.
What does spindle fiber attach to?
chromosomes
Chromatid pairs are fully visible the nucleolus and the nuleus membrane disintegrate and spindle fibers begin to form?
phophase
Chromatid pairs are fully visible the nucleolus and the nucleus membrane disintegrate and spindle fibers begin to form?
prophase
Fiibers extending from cell pole to cell pole are called what?
spindle fiber
What are the examples of mycoplasma?
spindle fiber disease
A muscle spindle is composed of several?
intrafusal fiber muscles embedded with the spindle along side the normal muscle fibers (extrafusal fiber muscles)
What is the role of kinetochores and microtubules?
Kinetochore allows the attachment of chromosomes to the spindle fiber, which is made ofmicrotubules.Microtubules allowssister chromatidsto separate duringcell division.
