These systems can exist as constructs of metal-oxide semiconductors and silicon as in a digital computer or in the wetware of organic compounds proteins and nucleic acids that make up biological organisms. We propose that there are essential functional properties of centralized information-processing systems for digital computers these properties reside in the computer s hard drive and for eukaryotic cells they are manifest in the DNA and associated structures. Methods Presented herein is a descriptive framework that compares DNA and its associated proteins and sub-nuclear structure with the structure and function of the computer hard drive. We identify four essential properties of information for a centralized storage and processing system 1 orthogonal uniqueness 2 low level formatting 3 high level formatting and 4 translation of stored to usable form. The corresponding aspects of the DNA complex and a computer hard drive are categorized using this classification. This is intended to demonstrate a functional equivalence between the components of the two systems and thus the systems themselves. Results Both the DNA complex and the computer hard drive contain components that fulfill the essential properties of a centralized information storage and processing system. The functional equivalence of
