Term:monopolar spindle attachment to meiosis I kinetochore
go back to main search page
Accession:GO:0051455 term browser browse the term
Definition:The process in which spindle microtubules become physically associated with the proteins making up the kinetochore complex during meiosis I. During meiosis I sister kinetochores are lying next to each other facing the same spindle pole and monopolar attachment of the chromatid to the spindle occurs.
Comment:Note that the synonym 'monopolar attachment' refers to the normal attachment of sister chromosomes to the spindle in meiosis I, and not to the aberrant attachment of sister kinetochores to a single pole in mitosis.
Synonyms:exact_synonym: attachment of spindle microtubules to kinetochore involved in homologous chromosome segregation;   attachment of spindle microtubules to kinetochore involved in meiosis I;   monopolar attachment;   sister kinetochore mono-orientation
 related_synonym: attachment of spindle microtubules to kinetochore during meiosis I
