Information and Function
If we want to build a low-cost computer, we buy components and build it. Three essential features are involved: (i) instructions for how to assemble, (ii) parts, and (iii) assembler. In a biological system, these components are also present, but the situation is more complex: The assembler must be part of the system, and the system must be self-reproducing. The structure of such a system is schematically shown in Fig. 2.1.
