WebThe 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] Each human cell contains around two metres of DNA, which must be tightly folded to fit inside the cell nucleus. However, in order for the cell to function, proteins must be able to access the sequence information contained within the DNA, in spite of its tightly-packed nature. Hence, the cell has a number of mechanisms in place to control how DNA is organized. Moreover, nuclear organization can play a role in establishing cell identity. Cells within an organ… incertus definition
