Phenomena of Life and Death Based on Nonphysical Gene and Computer Model of Organism
P. A. Wahid

Abstract
Genetic program (biological information), the driving force of life, is currently believed to be the information encoded by a chemical structure, DNA. The molecular gene (genome) concept is founded on this view. It now faces considerable conceptual problems and is examined here vis-à-vis nonphysical gene originally proposed by Wilhelm Johannsen. Molecular gene also fails miserably to explain the phenomena of life and death. Nonphysical gene is conceived in the light of computer model of organism. Organism is natural biocomputer or more precisely biorobot. It has both hardware and software. The computer model treats biological information (biosoftware) as information stored on the chromosome like the software of a computer stored on its hard disk. The chemical structures in the cell including DNA constitute the hardware. Life can be defined as the manifestation of the execution of the instructions carried in the biosoftware, and death as the result of deletion of the biosoftware from the biosystem. A dead body is like a computer without software. This will explain why a dead cell cannot be cultured and life cannot be created through chemical means. Computers, robots, etc. that run on man-made software can be considered as forms of artificial life.
