The RNA-protein world

Abstract

Following the naming of the RNAWorld for the hypothetical biochemical world during very early life forms, the current world was named the Protein World. However, the astonishing high level of transcripts from virtually all chromosomes in an organism now found in eucaryotes, as well as their extensive roles in regulating gene expression, suggests that today's world should be labeled as the RNA-Protein World.
