Question
Chapter 16, Problem 7TYU
Summary Introduction
To discuss:
The process of evolution and natural selection in cancer cells as per the details of evolution given in chapter 1.
Introduction:
Cancer cells are the cells that have the ability to divide uncontrollably. Cancer cells have distinct features than normal cells. The cytoplasm is reduced, multiple nuclei are present, chromatin is coarse, and nucleoli are also multiple and enlarged in cancerous cells.
