nucleolo-comb. form

Stress is usually determined by a subsequent element and vowels may be reduced accordingly.

Origin: Formed within English, by compounding. Etymons: nucleolus n., -o- connective.

Etymology: < nucleolus n. + -o- connective.Formations in English are found from the mid 19th cent. (see e.g. nucleolo-nucleated adj. ). Compare German nucleolo- (formations in which are found from at least the late 19th cent., e.g. Nucleolo-Centrosoma (see nucleolo-centrosome n. )), and Spanish nucleolo- (formations in which are found from at least the mid 20th cent., e.g. nucleolonema nucleolonema n.). N.E.D. (1907) gives only the pronunciation (niuklī·ŏlo) /njuːˈkliːələʊ/.

Biology.

Forming nouns and adjectives with the sense ‘of or with a nucleolus’.

nucleolo-centrosome n.

[after German Nucleolo-Centrosoma (J. Keuten 1895, in Zeitschr. f. Wissensch. Zool. 60 219)] now disused an endosome in the nucleus of the protist Euglena, likened to a centrosome in function.

1900 E. B. Wilson Cell (ed. 2) 34 The nucleolus is shown..to be comparable with an attraction sphere or centrosome (nucleolo-centrosome).

1938 Q. Rev. Biol. 13 397/2 Early observations of Euglena revealed a large intranuclear body which divides during mitosis and seems to lead the chromosomes in separating. This body was designated a nucleolo-centrosome; we may for the present call it by the term endosome, which implies an internal body without specifying its nature.

nucleolo-cytoplasmic adj.
