In this diagram of a duplicated chromosome, (2) identifies the centromereâthe region that joins the two sister chromatids, or each half of the chromosome.he centromere (centro- + -mere) is the part of a chromosome that links sister chromatids. During mitosis, spindle fibers attach to the centromere via the kinetochore. Centromeres were first defined as genetic loci that direhromosomes.
A replicated chromosome contains two identical double strand-DNA-molecules, the chromatids, that are joined at their centromere. Two single sets of pairs (daughter) chromosomes are formed by separation of the pair of chromatids during cell division (from anaphase on in mitosis and anaphase II in meiosis).Haploid is the term for a cell or an organism with only one set of chromosomes (n). The centromere (centron = middle, meros = part) is the region of the chromosome where the chromatids that arise from replication are held together. 2  The centromere hosts the kinetochore, a protein complex where the spindle filaments attach during mitosis or meiosis.
