Presumably ribosome and transfer RNA (tRNA) evolved from a pre-existing function in the RNA stage of life and were secondarily adapted for protein synthesis. Various possible initial functions of the primitive ribosome (protoribosome) have been suggested. The initial function of the primitive riboso
The ribosome is proposed to have evolved from an ancestor that simultaneously replicated and translated template RNA. At its decoding site, this ancestor to the ribosome carried a ribozyme that assembled product RNA by sequentially ligating anticodon triplets excised from tRNAs. This ribozyme was th
