| 释义 | anaphase noun[ U or C ] uk /ˈæn.ə.feɪz/ us /ˈæn.ə.feɪz/ the stage during cell division in which the two sets of chromosomes divide and move apart细胞分裂的后期 Cells actin anti-platelet assort axoplasm basal cell histography homologous chromosomes infiltration intercellular intermitotic nerve fibre neurofibril neurofibrillary neuroglia neuroglial tetrad thrombocyte thymocyte turgor unciliated You can also find related words, phrases, and synonyms in the topics: Genetics anaphase | American Dictionaryanaphase noun[ U ] us/ˈæn·əˌfeɪz/ biology the stage during cell division when the two sets of chromosomes (= cell structures that control what an organism is like) divide and move apart Examples of anaphaseanaphase We postulate further that this primary lesion leads in turn to failures in other components of the machinery involved in chromosome separation at anaphase. The irregularity of chromosome separation was displayed as chromosome bridges between daughter nuclei in anaphase and telophase. Calcium rises abruptly and briefly throughout the cell at the onset of anaphase. Saccharomyces cerevisiae kinesin- and dynein-related proteins required for anaphase chromosome segregation. The checkpoint delaying anaphase in response to chromosome monoorientation is mediated by an inhibitory signal produced by unattached kinetochores. In this pairing, anaphase is not only delayed but is partially reversed with the redispersal of chromosomes on an abortive metaphase spindle. The anaphase and telophase spindles possessed both a prominent array of interzone microtubules and asters. However, we did not observe significant differences in the anaphase/metaphase ratio of mutant and control larvae. This occurs in the absence of, or as an alternative to, the anaphase/telophase transition. This is a representative embryo that was fixed during the metaphase/anaphase transition of the first cell division cycle. Mosaicism could arise through several mechanisms including abnormal cell divisions (mitotic non-disjunction or anaphase lag), failure of cytokinesis or endoreduplication. Intracellular free calcium and mitosis in mammalian cells: anaphase onset is calcium modulated, but is not triggered by a brief transient. The role of calcium ions during mitosis: calcium participates in the anaphase trigger. In the second meiotic divisions, chromosome breaks and chromatin bridging at anaphase were observed. Therefore, anaphase could not be initiated as long as the chromosomes were not properly linked to the spindle microtubules. These examples are from corpora and from sources on the web.
