The structure that acts as a scaffolding for chromosomal attachment and movement is called what?
The first one is vague. The answer could be the mitotic spindle. It might be kinetochore microtubules. It might be talking about the kinetchores on the chromosomes instead of the microtubules that attach to the kinetochores. It could possibly even be talking about the centromeres, though to me that seems less likely. Neurons in the adult brain (and mature muscle cells?) do not routinely undergo cell division.
