Guida verificata passo dopo passo1
Understand the context: The mitotic spindle is a structure involved in cell division, specifically during mitosis, where it helps segregate chromosomes into the daughter cells.
Identify the components: The mitotic spindle is primarily composed of microtubules, which are dynamic structures made of tubulin proteins.
Differentiate between options: Intermediate filaments, collagen fibers, and actin filaments are other types of cytoskeletal elements, but they do not form the mitotic spindle.
Recall the function of microtubules: Microtubules are responsible for the movement of chromosomes during mitosis, as they attach to the chromosomes at the kinetochores and help pull them apart.
Conclude with the correct answer: Based on the function and composition, the mitotic spindle is made of microtubules.
