Question
Chapter 6.3, Problem 3CC
Summary Introduction
To explain: The process at molecular level as the chromosomes becomes shorter and thicker during cell division.
Concept introduction: Cell division is a natural process in which a parent cell divides into two daughter cells. In cell nucleus, DNA is present as chromosomes.

- Let’s model mitosis. Focus on drawing the cell nucleus taking care to model the number and location of chromosomes. Although the chromosomes are only visible in each stage, draw them in all stages for clarity sake. Draw a 2n=4 cell at G1 of interphase. Draw the same cell at the start of prophase. Draw the same cell at metaphase. Draw the cell(s) that result at the end of cytokinesis. You can draw this out on paperarrow_forwardLet’s model mitosis.

- 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.
