General Information
Term initial mitotic spindle pole body separation ID (Ontology) GO:0000073 (Gene Ontology)
Definition The release of duplicated mitotic spindle pole bodies (SPBs) that begins with the nucleation of microtubules from each SPB within the nucleus, leading to V-shaped spindle microtubules. Interpolar microtubules that elongate from each pole are interconnected, forming overlapping microtubules. Capturing and antiparallel sliding apart of microtubules promotes the initial separation of the SPB.
