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)
Together, the G1, S, and G2 phases make up the period known as interphase. Cells typically spend far more time in interphase than they do in mitosis. Of the four phases, G1 is most variable in terms of duration, although it is often the longest portion of the cell cycle (Figure 1).
