RNA processing in evolution. The logic of soft-wired genomes.

Abstract excerpt

Direct read-out of information from DNA into RNA allows the genome to be faithfully reproduced in RNA. This outcome occurs in what may be called "hard-wired" organisms. On the other hand, in what we refer to as "soft-wired" organisms, RNA is processed extensively, allowing a number of different messages to be produced from the same gene. As a consequence, the nucleotide sequences present in RNA (referred to here...
