A polymerase enzyme must be needed to transcribe a RNA or replicate a DNA sequence a. But how the 1st polymerase was produced from the genetic material when the ancient cell was born?
That is a question that is often debated. Some believe that zeolite minerals were involved in the first RNA polymerizations leading to the RNA world hypothesis. The RNA is then thought to have catalyzed peptide formation with compartmentalization using lipid membranes having come last.
