Gap 0 phase

Definition

noun

The dormancy period in the interphase or cell cycle in which the eukaryotic somatic cell is resting or dormant


Supplement

The Gap zero or Gap 0 phase is one of the substages of the cell cycle marked by the cell's quiescence, i.e. the cell is neither replicating its DNA nor preparing itself to divide. Cells, such as nerve cells and heart muscle cells, enter Gap 0 phase and become differentiated. Other cells, such as liver and kidney parenchymal cells, may revert to becoming active again and eventually divide through mitosis.
