The origin of life, consciousness and gene editing

 DNA does not function as a naked molecule. It only acts within the cell. Molecular mechanisms in the cell read the information in the DNA and translate this into hundreds of proteins used in the body for a myriad of functions. The transcription and translation of genetic information is achieved via a complex information-processing system utilising many types of nucleic acids (mRNA, tRNA, and others) and many specific enzymes. These form a tightly integrated system of systems. 

More than a hundred highly complex proteins are involved in translation. The paradox therein has not escaped commentators, these proteins cannot themselves be made except by DNA. The late British philosopher Sir Karl Popper mused for example: 

“What makes the origin of life and the genetic code a disturbing riddle is this: the code cannot be translated except by certain products of its own translation.”

In simple terms, the cell presents a chicken and egg paradox. It is impossible to decide which came first – proteins or DNA. Cells present a complex system of multiple interdependent parts and it is therefore hard to imagine how the whole system came into being. It is a self-referral system which functions holistically.

Self-referral systems point to fundamental principles and laws that characterise the search for unified field theories of physics.
