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 else can I help you with?
How many chromosomes attach to each spindle fiber during metaphase 1?
Two chromosomes attach to each spindle fiber during metaphase I of meiosis.
Which structure forms in prophase along which the chomosomes move?
spindle fiber
What do you predict would happen if the spindle fibers were disrupted during the metaphase?
If the spindle fiber were disrupted, the duplicated chromosomes would not be separated.
What phase is when each chromosome is connected to a spindle fiber?
The phase where each chromosome is connected to a spindle fiber is called metaphase. During metaphase, the chromosomes align at the metaphase plate at the center of the cell, and each chromosome is attached to spindle fibers emanating from opposite poles of the cell.
What does not belong cleavage furrow cytokinesis spindle fiber cell plate?
Cleavage furrow.Cell plate formation only occurs in plant cells. Spindle fiber is found in plant cells and cytokinesis occurs in plant cells.Cleavage furrow doesn't occur in plant cells and is the only one not to.
What does spindle fiber attach to?
chromosomes
What attaches the spindle fiber to the chromatid?
the kinetochore
A muscle spindle is composed of several?
intrafusal fiber muscles embedded with the spindle along side the normal muscle fibers (extrafusal fiber muscles)
How many chromosomes attach to each spindle fiber during metaphase 1?
Two chromosomes attach to each spindle fiber during metaphase I of meiosis.
Which structure forms in prophase along which the chomosomes move?
spindle fiber
What do you predict would happen if the spindle fibers were disrupted during the metaphase?
If the spindle fiber were disrupted, the duplicated chromosomes would not be separated.
Do centromeres divide in meiosis anaphase 1 or 2?
at anaphase 2. IN matephase 1 the spindle fiber attach to one spindle fiber. in anaphase 2 they attach to two spindle fibers then divide and move to opposite ends of the cell. now each is an individual chromosone
Do centromeres divide at anaphase one or two?
They divide at Anaphase two. In Matephase one the spindle fibers attach to one spindle fiber.
What phase is when each chromosome is connected to a spindle fiber?
The phase where each chromosome is connected to a spindle fiber is called metaphase. During metaphase, the chromosomes align at the metaphase plate at the center of the cell, and each chromosome is attached to spindle fibers emanating from opposite poles of the cell.
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
What structure forms in prophase along which chromosomes move?
Spindle fiber :d
What organizes spindle fiber in plant cell?
Mtoc... Microtubule organizing center....
