cytokinesisn.

Brit.

/ˌsʌɪtə(ʊ)kᵻˈniːsɪs/, U.S.

/ˌsaɪdəkəˈnisᵻs/

Forms: 1900s kytokinesis, 1900s– cytokinesis.

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: cyto- comb. form, -kinesis comb. form.

Etymology: < cyto- comb. form + -kinesis comb. form, after German Kytokinese (1898 in the source of which quot. 1898 is a summary). Compare earlier cytokinetic adj. and karyokinesis n. at karyo- comb. form .

Biology.

The processes occurring in the cytoplasm of a cell (as opposed to the nucleus) during cell division; the division of the cytoplasm of a cell into newly formed daughter cells.

1898 Jrnl. Royal Microsc. Soc. 517 There is [in spermatogenesis] what may be called a futile attempt at continued cell-division—a ‘kytokinesis’ without karyokinesis.

1928 E. B. Wilson Cell (ed. 3) ii. 116 It is often convenient to employ the term cytokinesis..to designate the..changes taking place in the cytoplasmic cell-body.

1958 Amer. Jrnl. Bot. 45 728/2 The sister nuclei reach their maximum separation in early telophase; thereafter they approach each other as cytokinesis proceeds.

1983 B. Alberts et al. Molecular Biol. Cell ix. 529 In some algae that contain only one or a few chloroplasts, the organelle divides just prior to cytokinesis.

2006 Science 20 Oct. 389/1 Once inside the target host cells, ExoT inhibits cytokinesis, the process by which daughter cells are physically separated during cell division.
