c. A cell can remain in G1 for weeks or much longer.

d. Proteins are formed throughout all subphases of interphase.

e. Histones are synthesized primarily during S phase.

4. Which statement about mitosis is not true?

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
