Abstract

Although proteins are essential components of all aspects of cell structure and function, they are not sufficient for their own propagation. Instead, the information necessary to specify each individual protein is stored in nucleic acids. The ‘central dogma’ of molecular biology states that sequence information can be transferred among nucleic acids, and from nucleic acids to proteins, but sequence information cannot be transferred among proteins, or from proteins to nucleic acids.
