Two sister chromatids (half a chromosome) join together at a protein junction called a centromere. Chromosomes are normally visible under a light microscope only when the cell is undergoing mitosis.ompaction of the duplicated chromosomes during cell division (mitosis or meiosis) results either in a four-arm structure (pictured to the right) if the centromere is located in the middle of the chromosome or a two-arm structure if the centromere is located near one of the ends.
Centromere. Definition. noun, plural: centromeres. (1) The constricted region joining the two sister chromatids that make up an X-shaped chromosome. (2) The site where kinetochore is formed. Supplement. Centromere is important particularly during mitosis.
