This module introduces the nucleoplasmic index in the context of understanding how the volume of organelles and cell contents change during the cell cycle. It is intended for an introductory biology audience.
Student Introduction: As cells pass through the cell cycle, their nuclear volume doubles in preparation for division into two daughter cells. When cells are in resting condition, however, the ratio of nuclear volume to cytoplasmic volume remains stable. This ratio is known as the nucleoplasmic index.
