To explain: How the motor proteins generate coordinated movement of individual microtubules rather than engaging in a tug-of-war.
Introduction: The microtubules are hollow and cylindrical in structure. They are approximately 25 nm in diameter, present in all eukaryotic cells and play crucial roles in the determination of s cell shape and also in cellular motility. It is composed of αβ-tubulin having two subunits such as α-tubulin and β-tubulin. The β-tubulin subunits are exposed at the plus ends and α-tubulin subunits are exposed at the minus ends. Kinesis and dyneins are two motor proteins that move along the microtubules.
To determine: The direction, in which microtubules crawl on a bed of kinesin molecules.
