The mitotic spindles arise from where
WebMicrotubules are polymers of tubulin that form part of the cytoskeleton and provide structure and shape to eukaryotic cells. Microtubules can be as long as 50 micrometres, as wide as 23 to 27 nm and have an inner diameter … WebDec 3, 2008 · Mitotic spindles are microtubule-based structures that separate chromosomes during mitosis. In most animals and fungal cells, spindle microtubules nucleate from centrosomes or spindle pole bodies.

WebThe mitotic phase is a multistep process during which the duplicated chromosomes are aligned, separated, and move into two new, identical daughter cells. The first portion of the mitotic phase is called karyokinesis, or nuclear division. WebOutside the nucleus, the mitotic spindle begins to form, which is composed of …
