|
Centrioles assist during cell division by helping distinegrate the nuclear membrane and then reform it.

|
Centrioles assist during cell division by latching onto the chromosomes’ centromeres with their spindles and pulling them apart into two sister chromatids.

Centrioles assist during cell division by replicating the cell’s DNA to prepare for synthesis.

Detailed explanation-1: -And when the chromosomes are condensing to undergo mitosis, the centrioles form the areas that mitotic spindle forms from. And those mitotic spindles go and attach to each of the chromosomes and pull the chromosomes to opposite ends of the cell to allow cytokinesis, then, to occur.
Detailed explanation-2: -Centrioles help to arrange the microtubules that move chromosomes during cell division to ensure each daughter cell receives the appropriate number of chromosomes. Centrioles are also important for the formation of cell structures known as cilia and flagella.
Detailed explanation-3: -In G2, centrioles recruit many proteins in preparation for mitosis, including microtubule regulators; this is called centrosome maturation. Centrosomes then separate physically at the entrance of mitosis, each one migrating to one of the poles of the spindle, to which they remain associated.
Detailed explanation-4: -Centrioles are responsible for organizing the spindle fibers in the mitotic spindle apparatus and are thought to participate in the completion of cytokinesis during the process of cell division.
Detailed explanation-5: -Long protein fibers called microtubules extend from the centrioles in all possible directions, forming what is called a spindle. Some of the microtubules attach the poles to the chromosomes by connecting to protein complexes called kinetochores.
