释义

Definition of karyokinesis in English:

karyokinesis

nounˌkarɪəʊkɪˈniːsɪsˌkarɪəʊkʌɪˈniːsɪsˌkɛriəkəˈnisəs
mass nounBiology
  • Division of a cell nucleus during mitosis.

    Example sentencesExamples
    • This analysis showed that rhb1 - D121A mutants arrested as small, round cells without detectable defects in karyokinesis or cytokinesis.
    • Whether the phenomena of karyokinesis are essentially chemical or not remains to be determined by further investigations.
    • Additionally, cytokinesis blocked cells are thought to be prone to polyploidization if the gap between the daughter nuclei is very small, resulting in incomplete or absent karyokinesis.
    • Note that macronuclear karyokinesis and cytokinesis has initiated in rad 51 nulls despite the failure to complete micronuclear mitosis.
    • But different proportions of mononucleated and binucleated myocytes may be present, and this possibility complicates the distinction between karyokinesis and cytokinesis.

Origin

Late 19th century: from karyo- 'cell nucleus' + Greek kinēsis 'movement' (from kinein 'to move').
