"The centrosome is the main MTOC (microtubule organizing center) of the cell during mitosis. Each centrosome is made up of two cylinders called centrioles, oriented at right angles to each other. The centriole is formed from 9 main microtubules, each having two partial microtubules attached to it. Each centriole is approximately 400 nm long and around 200 nm in circumference.

Web27 mei 2003 · Chromosome segregation is directed by the kinetochore, the chromosomal site of attachment to dynamic polymers called microtubules (MTs). Although the fidelity of chromosome segregation depends on precise interactions between kinetochores and MTs, it is still unclear how this interaction is mediated and regulated.

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.
