Why is the structure responsible for the movement of chromosome during anophase?
The Centrosome. It forms Centrioles which form spindle fibers. Some of the spindle fibers attach to the Kinetochore located on the Centromere of chromosomes. The spindle fibers work in conjunction with motor proteins to facilitate disjunction.
What stage centrioles separate?
Prophase- during prophase, chromatids shorten and thicken, nucleoli disappears, spindle fibers form and centrioles in animal cells move to opposite ends.
What cellular structures move to opposite ends of the cell during prophase?
It's the CENTRIOLES and their star-like radiating structures, called asters.This is Stage 1 in Mitosis:Chromatin in the nucleus condenses to form chromosomes. The pairs of centrioles move to the opposite sides of the nucleus. Spindle fibers form a bridge between the ends of the cell. The nuclear envelope breaks down.
What is responsible for forming spindle during mitosis?
The centrioles within the cell form the mitotic spindle.
What is found in only animal cells and helps with cell division by pulling apart chromosomes?
The organelles in question are the centrioles. During cell division, the centrioles move to oppose poles of the cell and synthesise the microtubules that make up the spindle apparatus, which separates the sister chromatids during the stage of anaphase.
What organelles form the asters and the spindle fibers?
The centrioles in animal cells form the asters and the spindle fibers.
The microtubules that form centrioles and spindle fibers are made of hollow tubes of?
protein
Do spindle fibers form in plant cells undergoing mitosis?
In metaphase, spindle fibers grow and attach to chromosomes. In anaphase, they pull the chromosomes apart. In telephase, they disappear.
What forms spindle fibers?
I believe that they are formed by the Centrioles in the cell. These centrioles are found inside (encased) in the centrosomes. They combine microtubles and associated proteins (such as Aurora A) to strengthen the spindle fibers.
Are thin tubes that form between the centrioles?
Spindle Fibers

What are the fibers that form around centrioles of an animal cells during the reproduction of the nucles?
Spindle fibers form from centrioles of animal cells during chromosomal separation in mitosis. These fibers elongate to reach the kinetochores of chromosomes, and then retract via depolymerization from each end of the dividing cell leading into cytokinesis.
What stage centrioles separate?
Prophase- during prophase, chromatids shorten and thicken, nucleoli disappears, spindle fibers form and centrioles in animal cells move to opposite ends.

What is responsible for forming spindle during mitosis?
The centrioles within the cell form the mitotic spindle.
Explain why prophase is the longest phase in mitosis?
because the most things happen in it. centrioles grow, spindle fibers arrange on chromosomes, and the cell grows exponentially.

The organelles in question are the centrioles. During cell division, the centrioles move to oppose poles of the cell and synthesise the microtubules that make up the spindle apparatus, which separates the sister chromatids during the stage of anaphase.
