pl.
of Nucleus
n.
One of a class of compounds, generally but not always distinguished by their sour taste, solubility in water, and reddening of vegetable blue or violet colors. They are also characterized by the power of destroying the distinctive properties of alkalies or bases, combining with them to form salts, at the same time losing their own peculiar properties. They all contain hydrogen, united with a more negative element or radical, either alone, or more generally with oxygen, and take their names from this negative element or radical. Those which contain no oxygen are sometimes called hydracids in distinction from the others which are called oxygen acids or oxacids.
a.
Sharp and harsh, or bitter and not, to the taste; pungent; as, acrid salts.
a.
Containing many nuclei.
n.
A substance associated with nuclein in cell nuclei, and by some considered as the fundamental substance of the nucleus.
n.
A sour substance.
a.
Caustic; bitter; bitterly irritating; as, acrid temper, mind, writing.
n.
A constituent of the nuclei of all cells. It is a colorless amorphous substance, readily soluble in alkaline fluids and especially characterized by its comparatively large content of phosphorus. It also contains nitrogen and sulphur.
a.

Of or pertaining to a nucleus; as, the nuclear spindle (see Illust. of Karyokinesis) or the nuclear fibrils of a cell; the nuclear part of a comet, etc.
a.
Causing heat and irritation; corrosive; as, acrid secretions.
n.
A double star; -- applied to the nucleus of a cell, when, during cell division, the loops of the nuclear network separate into two groups, preparatory to the formation of two daughter nuclei. See Karyokinesis.
