These straight, hollow cylinders are found throughout the cytoplasm of all eukaryotic cells and perform a number of functions.
Microtubules can function individually or join with other proteins to create larger structures.
These filaments are composed of linear polymers of tubulin, which are globular proteins, and can increase or decease in length by adding or removing tubulin proteins. All Rights Reserved .
