Labels:bulletin board | reckoner OCR: Let uS assume investigators could prove that ribonucleotides were able to emerge nonenzymatically. Workers who favor the simple scenario described above would still have to demonstrate that the nucleotides could assemble into polymers and that the polymers could replicate without assistance from proteins. Many researchers are now struggling with these challenges Once again minerals could conceivably have catalyzed the joining of reactive nucleotides into polymers Indeed James P Ferris of the Rensselaer Polytechnic Institute finds that a clay montmorillonite catalyzes the synthesis of RNA oligonucleotides Itis harder to conceive Of the steps by which RNA might have begun to replicate in the absence of proteins Early work in my laboratory initially suggested that such replication was possibl ...
