Textbook Question
Chapter 9.6, Problem 1HYEW
The saliva of dogs, like the saliva of most mammals (including humans), contains enzymes, antibacterial compounds, and growth factors. When a dog licks a wound, it not only cleans out some of the dirt and kills some of the bacteria that may have entered, but also leaves growth factors behind. The growth factors speed up the synthesis of cyclins, thereby stimulating the division of cells that regenerate the skin, helping to heal the wound more rapidly.

When some cancer cells produce growth factors that stimulate their own division leading to continuous self-
stimulation for cell division it is referred to as

A) normal body cells other than sperm and egg
B) pluripotent cells
C) most stem cells
D) all of the above are somatic cells

A) Cancer cells do not replicate their DNA.
B) Cancer cells replicate their DNA too quickly.
C) Cancer cells do not go through interphase during their cell cycle.
D) Cancer cells spend more time dividing compared to typical cells.
E) Cancer cells do not always grow to the same size as typical cells.
