WebNC ratio. Nuclear-cytoplasmic ratios. The nuclear-cytoplasmic ratio (also variously known as the nucleus:cytoplasm ratio, nucleus-cytoplasm ratio, N:C ratio, or N/C) is a measurement used in cell biology. It is a ratio of the size (i.e., volume) of the nucleus of a cell to the size of the cytoplasm of that cell. [1] WebNational Center for Biotechnology Information krylon red pepper spray paint
