Jd. Sutherland et Jm. Blackburn, KILLING 2 BIRDS WITH ONE STONE - A CHEMICALLY PLAUSIBLE SCHEME FOR LINKED NUCLEIC-ACID REPLICATION AND CODED PEPTIDE-SYNTHESIS, Chemistry & biology, 4(7), 1997, pp. 481-488
To understand how life began, we must explain the origins of nucleic a
cid replication and genetically coded peptide synthesis. Neither of th
ese is easy to explain individually; here, we propose a chemically pla
usible scheme for the evolution of a process that simultaneously produ
ced both polymers. Later, two separate machineries could have evolved
from the linked process.
