Cell Cycle Journals

The Cell Cycle is a 4-stage process consisting of Gap 1 (G1), Synthesis, Gap 2 (G2) and Mitosis. An active eukaryotic cell will undergo these steps as it grows and divides. After completing the cycle, the cell either starts the process again from G1 or exits the cycle through G0. From G0, the cell can undergo terminal differentiation.

G1 phase Cell increases in size Cellular contents duplicated S phase DNA replication Each of the 46 chromosomes (23 pairs) is replicated by the cell G2 phase Cell prepares for cell division M phase Mitosis followed by Cytokinesis (cell separation) Formation of two identical daughter cells
