Distinguish between G 1 and G 2 phase.

Feature G 1 phase G 2 phase Occurrence G 1 phase is the first phase of interphase which is the period from the end of the cell division to the beginning of the DNA replication. G 2 phase is the last phase of interphase from the completion of DNA replication to the beginning of the cell division. Feature G 1 phase G 2 phase Responsibility G 1 phase is responsible for the determination of the fate of the cell whether it moves to next phase of the cycle or it will enter to the G 0 phase. G 2 phase is responsible for the preparation of proteins for the cell division. Feature G 1 phase G 2 phase cell organelles The number of cell organelles remains the same. Duplication of the cell organelles occurs in the G 2 phase.
