This document outlines an introduction to biochemistry course, beginning with a discussion of the diversity and spread of life, historical and philosophical perspectives on life, the role of technology in advancing understanding of life, and how views have evolved from a focus on molecules to modern molecular biology views of DNA, RNA and protein. It explores taxonomy and systems of life, as well as early microscopists' studies of cells and the concept of cells as the fundamental unit of life.

12. A Parting Thought
Excuse me for feeling superia,
to all of the lowly bacteria.
You should know very well,
there is no organelle,
inside of their tiny interia.
