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.

How to write the methodology? I have a practical of HOMOGENIZATION AND FREEZE-DRYING, I need to do a lab report, but I don't know how to write the methodology.
Here is the introduction:
HomogenizationHomogenization is a process that involves breaking apart cells to release theircytoplasm and its contents. When the purpose is to extract organelles, it is frequentlydone in two steps; first, using a blender to break the tissue up, and then with anultrasonic or mechanical tissue disruptor. The organelles are then generally separatedusing differential centrifugation.Freeze-dryingFreeze-drying also known as lyophilization, and it is a dehydration process typicallyused to preserve perishable material or make the material more convenient fortransport. It works by freezing the material and then reducing the surrounding pressureto allow the frozen water in the material to sublimate directly from the solid phase tothe gas phase.

Indicate the orientation of the preprophase band and the site where the new cell walls of the daughter cells will form.arrow_forwardBiologists 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.
