- Biologists have long been interested in the effects of radiation on cells. In one experiment, researchers examined the effect of radium on mitosis of chick embryo cells growing in culture. A population of experimental cells was examined under the microscope for the number of cells in telophase (as a measure of mitosis occurring) before, during, and after exposure to radium. The results are shown in the Figure. What is the effect of radium exposure on mitosis? Source: R. G. Canti and M. Donaldson. 1926. The effect of radium on mitosis in vitro.

- 1. Which among the lettered cells in Fig 2 are at interphase stage? 2. What mitotically important events occur in the cell during interphase? 3. What feature is labelled “V” in figure 2?19. The G2 checkpoint of the cell cycle triggers the start of mitosis. It is dependent upon the presence of cyclin. Cyclin production begins in the S phase and continues through the G2 phase. It is not the presence of cyclin alone. However, that allows the cell to pass the G2 checkpoint. Cyclin must first bind with kinase to form the following complex, an accumulation of which triggers mitosis. A. Cyclin-dependent complex B. Cyclin-kinase complex C. Mitosis progression factor D. Maturation promotion factor1. What structure on the chromosomes do the mictrotubule in the mitosis spindle attach to and drive the separation of the sister cell? Centrosome, kinetochore, minus end, cohesion complexes 2. The direction of cell cycle progression is: 3. Irradiated mammalian cells usually stops dividing and arrest at G1/ S checkpoint.
