How does duration affect the cell cycle in an organism?
Duration depends on the type of cell and other external factors such as temperature, food, and oxygen. The time period for G, S, G, and M-phase in different species under specific environmental conditions is like 20 min for bacterial cells, 10 hours for intestinal epithelial cells, 20 hours for onion root tip cells, etc. This shows that the time required for each step has been pre-set within cells of each organism.
