centromere /cen·tro·mere/ (-mēr) the clear constricted portion of the chromosome at which the chromatids are joined and by which the chromosome is attached to the spindle during cell division.centromer´ic
Centromere The centromere is the constricted region of a chromosome. It performs certain functions during cell division. Mentioned in: Cri Du Chat Syndrome, Prader-Willi Syndrome centromere (cen) [sen′trəmir] Etymology: Gk, kentron + meros, part the constricted region of a chromosome that joins the two chromatids to each other and attaches to spindle fibers in mitosis and meiosis. During cell division the centromeres split longitudinally, half going to each of the new daughter chromosomes. The position of the centromere is constant for a specific chromosome and is identified as acrocentric, metacentric, submetacentric, or telocentric. Also called kinetochore, kinomere, primary constriction. centromeric, adj. centromere the clear constricted portion of the chromosome at which the chromatids are joined and by which the chromosome is attached to the spindle during cell division.

Decreased expression of six RNA species was seen at various time points in all cell strains analyzed: plasminogen activator (PLAT), centromere protein F (CPF), replication factor C (RFC3), thymidylate synthetase (TYMS), a putative mitotic checkpoint kinase (BUB1), and a gene of unknown function (GenBank accession no. ``They occasionally talk about cellular structure and when they say centromere, I know what it looks like because I remember seeing them on slides here,'' he said. Any DNA that doesn't have a centromere, you don't want, even if it came from you," he says. |
