- 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.

Explain why this is the case and the detailed mechanism(s) of how these drugs inhibit microtubules that make them effective.Which statements are true? Explain why or why not.1 Since there are about 1013 cells in an adult human,and about 1010 cells die and are replaced each day, webecome new people every three years.2 In order for proliferating cells to maintain a rela-tively constant size, the length of the cell cycle must matchthe time it takes for the cell to double in size.3 While other proteins come and go during thecell cycle, the proteins of the origin recognition complexremain bound to the DNA throughout.4 Chromosomes are positioned on the metaphaseplate by equal and opposite forces that pull them towardthe two poles of the spindle.5 Meiosis segregates the paternal homologs intosperm and the maternal homologs into eggs.6 If we could turn on telomerase activity in all ourcells, we could prevent aging.
