You are growing a cell line in the lab, which you began on day and which you monitor every 24 hours, by looking at your cell culture plates under the microscope. At the first 24 hours check point, you observed cells growing well, by identifying cells in all the different stages of cells division. You refresh the medium and return culture plates to incubator. You continue this exerciser for 2 more days. Then on the 4th day, you look at your cells and discover that all the cells look like the image below. You continue with the experiment, because it is TOTALLY normal for ALL the cells to be in the same phase!
