1960 M. Fischberg & H. Wallace in J. S. Mitchell Cell Nucleus i. 31 These anucleolate embryos develop into apparently normal elongated neurulae and tailbud stages.
2005 Biol. Bull. 209 96/2 The subcellular structure of nondividing stages also corresponded to that of yeasts, consisting of an anucleolate nucleus..,abundant ribosomes, and an electron-clear multi-lamellar wall.
