What is responsible for forming spindle during mitosis?
The centrioles within the cell form the mitotic spindle.
What would be the immediate consequence of destroying a cell's centrosomes?
The mitotic spindle would not form
What happens to the chromatin during the prophase?
During prophase the chromosomes are identical chromatids connected at the center by a centromere, forming a X-shaped object. The distinguishing feature of prophase is the setup of the mitotic spindle, which is used to maneuver the chromosomes about the cell. The spindle is formed by excess parts from the dismantled cytoskeleton. The spindle is initially setup outside the nucleus. The cell's centioles are duplicated to form two pairs of centrioles. Each pair becomes the part of the mitotic center which forms the focus for an array of microtubules, called the aster. The two asters lie side by side close the the nuclear envelope. Near the end of prophase the asters pull apart and the spindle is formed. The mitotic spindle forms. The cell lines up and starts mataphase 1
Is the first phase of mitosis in which chromosomes condense and spindle microtubules begin to form.?
the phase of mitosis when chromosimes are ligned in the middle of the cell
What is the organelle that forms spindle fibers that split and pull chromosomes to opposite ends of the cell?
Nuclear envelope. It breaks down and it's microtubules form the fibers
What is a spindle made of?
a spindle fiber is a specialized form of microtubules...that's what it is made of
What does the mitotic spindle form from?
sai ganesh
One event occurring during prophase is?
The begining of the formation of the mitotic spindle-During prophase, the mitotic spindle begins to form.
What is responsible for forming spindle during mitosis?
The centrioles within the cell form the mitotic spindle.
During mitosis the centrioles form or organize the mitotic apparatus which is known as what?
spindle
The microtubules that form centrioles and spindle fibers are made of hollow tubes of?
protein
What would be the immediate consequence of destroying a cell's centrosomes?
The mitotic spindle would not form
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.
What form to help attach and move chromatids to the opposite poles of the cell?
Spindle Fibers

Are thin tubes that form between the centrioles?
Spindle Fibers
