Het kinetochoor is een schijfvormige eiwitstructuur, waar de spoelvezels zich hechten tijdens celdeling om zusterchromatiden uit elkaar te trekken. Het kinetochoor ontstaat nadat het chromosoom zich in twee splitst en zo de cel ook in twee splitst. Het kinetochoor is dus het overblijfsel van het centromeer aan beide delen van het chromosoom (beide chromatiden). Het kinetochoor bevindt zich ter hoogte van een centromeer (dit is een insnoering in het chromosoo… WebKinetochores are not 1. Formed by spindle Fibres 2. Formed by asters 3.
