The centromere is A. a protein composed of 8 subunits that binds to DNA. B. an A-T-rich region of the chromosome which may be bound by kinetochores. C. proteins that help pull apart sister chromatids at the telomeres D. the name given to a specific short (about 10 bases long) region of G-C rich DNA... show more The centromere is A. a protein composed of 8 subunits that binds to DNA.
Within the centrosome, the centrioles are positioned so that they are at right angles to each other, as illustrated in Figure 1. Each centriole is made of nine bundles of microtubules (three per bundle) arranged in a ring.Centrioles play a notable role in cell division.During interphase of an animal cell, the centrioles and other components of the centrosome are duplicated, though scientists are not yet sure how this duplication takes place.entrioles play a notable role in cell division.
