An aster is a cell biology cellular structure shaped like a star symbol star , formed around each centrosome during mitosis in an animal cell. ref Campell Biology , p.221 ref Astral rays, composed of microtubules , radiate from the centrosphere and look like a cloud. During mitosis, there are four stages of cell division Prophase , Metaphase , Anaphase , and Telophase . During prophase, two aster covered centrosomes migrate to opposite sides of the Cell nucleus nucleus in preparation of mitotic spindle formation. During metaphase, the astral rays connect to the lined up chromosomes at their centromere . Afterwards, during anaphase, the astral rays pull the chromosomes apart into its individual chromatids and pull them towards the centrosomes, located at opposite ends of the cell. This allows the cell to divide properly with each daughter cell containing full replicas of chromosomes. In some cells, the positions of the asters also determine the site of cell division.

Unreferenced stub auto yes date December 2009 Dicentric chromosome is an aberrant chromosome having two centromere s. Dicentric chromosomes form when two chromosome segments from different chromosomes or from the two chromatids of a single one , each with a centromere, fuse end to end, with loss of their acentric fragments. Dicentrics, despite their two centromeres, may be mitotically stable if one of the two centromeres is inactivated, or if the two centromeres always coordinate their movement to one or the other pole during anaphase. Such chromosomes are formally called pseudodicentric. The most common pseudodicentrics involve the sex chromosomes or the acrocentric chromosomes Robertsonian translocation . Evaluation of centromere function by Fluorescent in situ hybridization FISH combined with immunofluorescence analysis of centromere and kinetochore proteins is a specialized procedure in some clinical cytogenetics laboratories.

Cullins are a family of hydrophobic protein s providing a scaffold for ubiquitin ligase s. All eukaryotes appear to have cullins. They combine with RING finger domain RING proteins to form Cullin RING ubiquitin ligases CRLs that are highly diverse and play a role in a myriad of cellular processes. Human genome contains seven cullin genes CUL1 , part of SCF complex CUL2 , part of ECS complex Elongin C CUL2 SOCS box CUL3 , part of CUL3 BTB complex CUL4A CUL4B CUL5 CUL7 a more distant member called ANAPC2 , part of Anaphase promoting complex protein stub External links http pfam.sanger.ac.uk family?id Cullin Cullin family Sanger Institute website.

During mitosis or meiosis , the spindle checkpoint prevents Mitosis Anaphaseanaphase onset until all chromosome s are properly attached to the Spindle apparatus spindle . To achieve proper segregation, the two kinetochore s on the sister chromatid s must be attached to opposite spindle poles bipolar orientation . Only this pattern of attachment will ensure that each daughter cell biology cell receives one copy of the chromosome. Metaphase to Anaphase Transition The beginning of metaphase is characterized by the connection of the microtubules to the kinetochores of the chromosomes, as well as the alignment of the chromosomes in the middle of the cell. Each chromatid has its own kinetochore, and all of the microtubules that are bound to kinetochores of sister chromatids radiate from opposite poles of the cell. These microtubules exert a pulling force on the chromosomes towards the opposite ends of the cells, while the cohesion between the sister chromatids oppose this force. At the metaphase to anaphase transition, this cohesion between sister chromatids is dissolved, and the separated ..., the job of the metaphase checkpoint is to prevent this transition into anaphase until the chromosomes ... preventing the activation of the polyubiquitylation activities of anaphase promoting complex APC .
