Which of the following best describes the kinetochore? A structure composed of several proteins that associate with the centromere region of the chromosome and that can bind spindle microtubules. B. The centromere region of metaphase chromosome at which the DNA can bind with spindle proteins. C. The array of vesicles that will form between dividing nuclei and give rise to the metaphase plate. D. The ring of actin microfilaments that will cause the appearance of the cleavage furrow. E. The core of proteins that forms the cell plate in dividing plant cells.

Match the following structure or molecules with their function. Centromere Centriole Chromatin Cohesin Condensin Kinetochore Spindles protein that holds sister chromatids together consists of DNA and protein in uncoiled form during interphase microtubule organizing centers, found at the poles in animal cells microtubules that separate chromosomes duringcell division constriction on the chromosome, where cohesin and kinetochores bind protein that condenses the chromosomes attaches the spindle to the chromosomes, located at the centromere

Which best describes the kinetochore? A structure composed of several proteins that associate with the centromere region of a chromosome and that can bind to spindle microtubules. The array of vesicles that will form between two dividing nuclei and give rise to the metaphase plate. The ring of actin microfilaments that will cause the appearance of the cleavage furrow. The centromere region of a metaphase chromosome where the DNA can bind with spindle proteins.
