ABSTRACT
The Earth was a water world with a nonexistent continental crust, an extremely turbulent atmosphere, and a hydrosphere that was exposed to intense ultraviolet light. In most living organisms, deoxyribonucleic acid (DNA) is physically divided into “chromosomes,” packaged and organized structures among which DNA is distributed. The DNA of an organism is divided into a “coding” part, containing the genes that can produce proteins, and a “noncoding” part, which performs less obvious tasks. Cells are the basic structural, functional, and biological units of all known living organisms. Living organisms can replicate, and cells are the building blocks of all organisms. DNA and RNA contain the genetic information to both “run the cell” and also “replicate the cell”. Schrodinger’s ideas helped extend biochemistry from a discipline concerned with the role of enzymes in production and utilization of energy within a cell, to a discipline concerned with copying, transmission, and editing of information.
