â in cells capable of dividing, the period between cell divisions is called interphase â cells spend most of their time in interphase because this is the phase where they perform their functions (obtaining energy, synthesizing products, repair damage, fight disease, duplicate their genetic material and get ready for division)
Some 90 percent of a cell's time in the normal cellular cycle may be spent in interphase. 1  G1 phase: The period prior to the synthesis of DNA. 2  S phase: The period during which DNA is synthesized. 3  G2 phase: The period after DNA synthesis has occurred but prior to the start of prophase.
