Jutta Ellermann is a MSK fellowship trained Board Certified Radiologist with 10 years of clinical practice at the University of Minnesota with a special focus on MSK imaging research. Her areas of research interest include:
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)
Best Answer: Interphase is longest phase (90% of the cell cycle), divided into three sub-phases(G1,S, and G2). Only during the S phase does the cell replicate its DNA for the next cell division. Interphase lasts about 23 hours. But keep in mind a cell can go into G0 phase which keeps the cell from dividing.
