We think here of a helical molecule with 20 arrangements of 3 bases which de- fine the code information along the chain. Partly because the process re- sembles the meshing of carefully fitted gears, and partly because of the initials of the inventors of the theory, let us call it the cog theory. Figure 6-13 is a schematic representation of the cam and the cog. triplet base code. sugar ridge.
