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.
â¢ Kinetochores assembles on the centromere. â¢ Centromeres are clearly visible with a light microscope as a constricted region on the condensed chromosome while kinetochrores can only be seen with the aid of an electric microscope. â¢ Unlike in the centromeres, three different layers can be found in the kinetochore.
