WebWhere do kinetochores attach to chromosomes quizlet? To attach to microtubules, each chromosome has a specialized structure called a kinetochore. The kinetochore is located at the centromere (the constricted region of the condensed chromosome). Kinetochores contain many protein complexes to link the centromeric DNA eventually to microtubules. WebThe kinetochore microtubules shorten by depolymerization at their plus ends, and motor proteins associated with the kinetochores keep the chromatids linked to the shortened plus ends, retaining the attachment of the chromatids to the kinetochore microtubules. During anaphase B, the two spindle poles move further apart.
