Abstract

It is widely accepted that there exists a “resting” or “quiescent” state where a growing cell leaves the cell cycle to enter what is often called the “G0‐phase.” I propose that there is no biological reality to the “G0‐phase.” The experimental basis for proposing a G0‐phase is re‐examined and re‐analyzed here showing that the G0‐phase is an anthropomorphic construct with no biological reality.
