The Cell Cycle and Cell Di i iDivision
Events of the Cell Cycle Interphase – time when cell isn’t dividing – can be long. Made up of 3 phases: G1 – cells grow and create new proteins and organelles S – chromosomes replicated and make DNA G2 – shortest of the three phases and organelles required for cell division made...

Cell division is the most complex process undertaken by a single cell and must be stringently regulated to maintain fidelity of reproduction. Proliferative cells are in a continuous loop or cycle composed of four stages: S , during which DNA synthesis occurs, M (mitosis), G1 and G2. The ...
