In this article we will discuss about the Structure and Function of Microtubules and Cytoskeleton in Cell. Structure of Microtubules and Cytoskeleton in Cell: Microtubules are long, hollow tubular cylinders with an outer diameter of 250Å. The wall thickness is about 50Å, leaving a hollow core of about 150Å diameter. The length of microtubules varies from a fraction of a [...]
