👉 Microtubules are small, cylindrical structures that play a critical role in the cell cycle and protein synthesis. They consist of two types of proteins: actin and myosin. Microtubules are responsible for organizing and directing the movement of cells during the cell cycle. The microtubules are composed of microfilaments, which are long, cylindrical structures that form a network throughout the cytoplasm. The microfilaments have been shown to play a crucial role in various cellular
