What happens in a cell during interphase?

Expert Answers

Interphase is a step in the cell cycle and cells tend to spend most of their lifetime in this step. Cells enter the interphase after completing the M-phase. Interphase is divided into a number of phases: G1, S-phase and G2. G1 or Gap 1 is the phase during which the cell produces a number of proteins that are required for replication. As a result of this protein production, the cell bulks up and increases in volume. In the S-phase, this bulked up cell produces copies of the chromosomes, thus effectively doubling the DNA content of the cell. After S-phase, the cell enters the G2 or Gap 2 phase, during which the cell prepares for division by producing a number of proteins and dividing the mitochondria. 

The cells that do not divide enter G0 or Gap 0 phase, immediately after G1 phase.
