Centromere plays an essential role in proper chromosome segregation during mitosis and meiosis in eukaryotic cells. Centromere function includes sister chromatid adhesion and separation, microtubule attachment, chromosome movement, establishment of heterochromatin and mitotic checkpoint control.

The nucleus would never divide, and the new daughter cells would lack a nucleus and would die. What role does the centromere play in cellular reproduction? It is the area where the nucleus is during cell division. It is the area of alignment for the chromosomes.

The main difference between centromere and kinetochore is that centromere is the region where the two sister chromatids are held together after the replication of chromosome where kinetochore is the protein complex on the chromosome where spindle fibers are attached during cell division.

A chromomere, also known as an idiomere, is one of the serially aligned beads or granules of a eukaryotic chromosome, resulting from local coiling of a continuous DNA thread. In areas of chromatin with the absence of transcription, condensing of DNA and protein complexes will result in the formation of chromomeres.

Centrosome and centromere are two components involved in the division of a cell. A centrosome is an organelle which is made up of microtubules. The centromere is a region of DNA which is highly constricted to form a tiny area holding the two sister chromatids together during the cell division.

Cellular division has three main functions: (1) the reproduction of an entire unicellular organism, (2) the growth and repair of tissues in multicellular animals, and (3) the formation of gametes (eggs and sperm) for sexual reproduction in multicellular animals.
