Usually, measles has a typical rash but other viral exanthems (widespread rash) are similar or eczema and allergic skin rash.

Best Answer: The centromere..... The centromere is a region, often found in the middle of the chromosome, involved in cell division and the control of gene expression. At this centromeric constriction the two mostly identical halves of the chromosome, the sister chromatids, are held together until late metaphase. During mitotic division, a transient structure called kinetochore is formed on top of the centromeres.
