Perhaps you should read the actual abstract to the Lincoln- Joyce paper:-
"An RNA enzyme that catalyzes the RNA-templated joining of RNA was converted to a format whereby two enzymes catalyze each other's synthesis from a total of four oligonucleotide substrates. These cross-replicating RNA enzymes undergo self-sustained exponential amplification in the absence of proteins or other biological materials. "
Which of your misleading creationist sources implied that DNA and protein were used in the experiment?
Where did he say that DNA and Protein were used ? He is right, they only catalyzed a bond reaction nothing more. ItÃ‚Â´s ridiculous to call it self-replication.
