Software (In the nucleic acids), and Hardware (in the proteins)…?

Tuesday, January 21st, 2020

Hardware/software entanglement. As we shall see, all life of the sort found on Earth stems from a deal struck between two very different classes of molecules: nucleic acids and proteins. These groups complement each other in terms of their chemical properties, but the contract goes much deeper than that, to the very heart of what is meant by life. Nucleic acids store life’s software; the proteins are the real workers and constitute the hardware. The two chemical realms can support each other only because there is a highly specific and refined communication channel between them mediated by a code, the so-called genetic code. This code, and the communication channel — both advanced products of evolution — have the effect of entangling the hardware and software aspects of life in a baffling and almost paradoxical manner. – no capitulo What´s Life?
