What is the Structure of Kinetochore Microtubules?
Kinetochore microtubules are composed of tubulin proteins, arranged in a cylindrical structure. Each microtubule is made up of 13 protofilaments that form a hollow tube. The plus end of the microtubule is highly dynamic and interacts with the kinetochore, while the minus end is anchored at the spindle pole. The kinetochore itself is a multi-protein complex that serves as a critical interface between the chromosome and the microtubule.
