Chapter 9, Problem 10TYU
FOCUS ON INFORMATION
The continuity of life is based on heritable information in the form of DNA. In a short essay (100‒150 words), explain how the process of miles is faithfully parcels out exact copies of this heritable information in the production of genetically identical daughter 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.
