The '''G<sub>1</sub> phase''', '''gap 1 phase''', or '''growth 1 phase''', is the first of four phases of the [[cell cycle]] that takes place in [[eukaryotic cell]] division. In this part of [[interphase]], the cell synthesizes [[Messenger RNA|mRNA]] and [[proteins]] in preparation for subsequent steps leading to mitosis. G<sub>1</sub> phase ends when the cell moves into the [[S phase]] of interphase. Around 30 to 40 percent of cell cycle time is spent in the G<sub>1</sub> phase.
