While centrioles aren't made from tuberculin, they are crucial for organizing cell division in animal cells. They are made of microtubules, which are protein fibers that form the cytoskeleton.

Here's how they work:

* During cell division (mitosis or meiosis), centrioles replicate and move to opposite poles of the cell.

* They then form spindle fibers, which are made of microtubules and attach to the chromosomes.

* The spindle fibers pull the chromosomes apart, ensuring that each daughter cell receives a complete set of genetic material.

Tuberculin, on the other hand, is a purified protein from Mycobacterium tuberculosis, the bacteria that causes tuberculosis. It's used in the tuberculin skin test to diagnose tuberculosis infection.
