Centrioles are cylindrical structures found in animal cells that play a crucial role during cell division.
During mitosis, centrioles help organize the microtubules that form the mitotic spindle, which is essential for separating chromosomes into the daughter cells.
The mitotic spindle is composed of microtubules that attach to the chromosomes at the centromere, allowing them to be pulled apart during cell division.
Centrioles duplicate before mitosis begins, ensuring that each daughter cell receives a complete set of chromosomes.
While centrioles are important for spindle formation, they do not directly participate in DNA replication, cell cycle regulation, or cytokinesis.
