Cells in G 0 phase:

Quantrex Academy · Accepted Answer

Correct answer: A. Exit the cell cycle

The cells remain in an inert state in the G 0 phase of the cell cycle. Hence, G 0 can be either viewed as the distinct inert stage which occurs outside the cell cycle or as an extension to the G 1 phase, where cell neither divides nor prepares for it. Sometimes, G 0 is also referred to as &ldquo;post-mitotic&rdquo; state where cells in G 0 are in non-dividing phase in the outside of cell cycle. Some types of cells, such as nerve and heart muscle cells, become post-mitotic when they reach maturity (i.e., when they are terminally differentiated) but continue to perform their main functions for the rest of the organism's life. Multinucleated muscle cells which don&rsquo;t undergo cytokinesis are also thought to be in the G 0 stage. Hence, it suspends the cell cycle. G 0 stage represents actually indicates the arrest of cell cycle and onset of differentiation.
