Usually, measles has a typical rash but other viral exanthems (widespread rash) are similar or eczema and allergic skin rash.
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.
The other major function of the centromere is attaching the microtubules in the mitotic spindle. In this function, the centromere directs the formation of the kinetochore, which is a special protein structure that attaches to the microtubules in the mitotic spindle. On each chromatid, the kinetochore forms at the centromere region of the DNA.
