From the text:

"This document is dedicated to the memory of the late Professor Charles Lochmuller (right) of Duke University. Dr. Lochmuller was a good guy, a natural comic, and an eminent scientist.

Here I approach biochemistry in a new (I believe) way. It is tradition, starting with Lehninger's first Biochemistry textbook and continuing in essentially all subsequent biochemistry textbooks, to teach about each type of biopolymer in isolation of the others other. Protein DNA, RNA and carbohydrate are described in distinct, well-separated chapters as unrelated chemical phenomena.

In Part 2 of this document I present DNA, RNA, polypeptide, and polysaccharide in the context of their common attributes. Rather than focusing exclusively on the differences (amino acid side chains, nucleic acid bases, etc), I focus on the profound universal properties (self-complementarity, emergence, etc) that unite biopolymers. In my view only by learning about biopolymers in context of each other can one hope to achieve a reasonable understanding of them"
