1. G1 phase (G1 gap)
The period during interphase in the cell cycle between mitosis and the S phase (when DNA is replicated). Also known as the "decision" period of the cell , because the cell "decides" to divide when it enters the S phase. The "G" stands for gap.

2. Interphase
The period in the cell cycle when the cell is not reproducing (undergoing mitosis ). During this time, the cell is growing rapidly, increasing its size, making new molecules, and doing all of the things that cells do that are not associated with cell division. The period is subdivided into the g1 phase, the S phase , and the G2 phase.

3. Interphase
The period between cell divisions when growth and replacement occur in preparation for the next division; consists of gap 1 (g1), synthesis (S), and gap 2 (G2).

4. PH
A measure of the hydrogen- ion activity in a solution, expressed as the negative log10 of hydrogen ion concentration on a scale of 0 (highly acidic ) to 14 (highly basic ) with a pH of 7 being neutral.
