nucleolus

(nū-klē′ō-lŭs) plural.nucleoli [L., little kernel]
A spherical structure in the nucleus of a cell made of DNA, RNA, and protein. It is the site of synthesis of ribosomal RNA (rRNA); a cell may have more than one. Embryonic cells and those in malignancies actively synthesize rRNA; therefore, their nucleoli are larger than those of cells that do not require increased amounts of rRNA.
nucleolar (nū-klē′ō-lăr), adjective

nucleolar

pertaining to or emanating from nucleolus.
