Centrioles: Structure and Function

This video explores the fascinating world of centrioles, tiny organelles within cells that play crucial roles in cellular functions. It covers their unique structure, location within the centrosome, and their vital roles in microtubule organization, cell division, and the formation of cilia and flagella. The video also delves into the process of centriole duplication and the impact of defects leading to disorders known as kellyopathies. The presentation concludes with a call to action for viewers to continue exploring the wonders of science.
