What is the main role of centrioles during cell division?

The main role of centrioles during cell division is to anchor microtubules in the mitotic spindle. Centrioles are cylindrical structures found in animal cells and play a crucial part in organizing and facilitating the formation of the mitotic spindle, which is essential for separating chromosomes during mitosis. When a cell prepares to divide, centrioles replicate and move to opposite poles of the cell, helping to form the spindle fibers that attach to chromosomes. This anchoring ensures that chromosomes are properly aligned and separated into the daughter cells.

The spindle fibers are made up of microtubules, which are dynamic structures that can grow and shrink. The anchoring role of centrioles is vital for the correct distribution of genetic material, ensuring that each new daughter cell receives the appropriate number of chromosomes. This process is key to maintaining genetic stability across cell generations.

Other options do not accurately reflect the function of centrioles during cell division. While cytokinesis involves processes like the formation of the contractile ring, the centrioles are not directly involved in physically pinching the cell. Synthesis of new genetic material occurs during DNA replication in the S phase of the cell cycle, not mediated by centrioles. Storage of nutrients is unrelated to the
