What attaches the spindle fiber to the chromatid?
the kinetochore
A chromatid is attached to a spindle fiber by the what?
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.
What does spindle fiber attach to?
chromosomes
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.
What is the definition of prophase?
Prophase is the first step in Mitosis (part of interphase) and it's when the chromatid pairs become visible and the spindle is beginning to form.
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.
During metaphase the centrometers attach to what structures?
During metaphase, the centromeres of chromosomes attach to spindle fibers (microtubules) that extend from opposite poles of the cell. This attachment helps properly align the chromosomes along the metaphase plate in the center of the cell before they are separated in anaphase.
