WebCell cycle. About 78% of a cell’s life is spent in Interphase, growing and preparing itself for cell division. Interphase itself contains three subphases. Immediately after cell division, a newly-formed cell enters the Gap 1 or G1 portion of Interphase. During G1, cells actively grow and, in many cases, differentiate to perform specific ...
