The Longest Phase Of The Cell Cycle. During interphase, the cell acquires nutrients, creates and uses proteins and other molecules, and starts the process of cell division by replicating. Chemicals called mitogens signal cells to start dividing.cells competent to divide join the cell cycle in g1 phase and remain in this phase for a bit less than half of the total cell.

Interphase is the longest phase of the cell cycle. During interphase, the cell acquires nutrients, creates and uses proteins and other molecules, and starts the process of cell division by replicating. During this stage the genes are active and.
