==Prebiotic RNA Polymerization==
===From Clays===
Research from Rensselaer Polytechnic Institute suggests that the formation of long strands of RNA may have been catalyzed by clays such as montmorillonite. The charged clay surface attracts the nucleotides and the increased local concentration of nucleotides causes bond formation between nucleotides, forming a polymer of RNA.<ref>http://www.rpi.edu/dept/chem/chem_faculty/profiles/pdfs/ferris/Royal_Soc..pdf</ref><ref>http://www.rpi.edu/dept/chem/chem_faculty/profiles/pdfs/ferris/Alders.Mass_Spec.pdf</ref><ref>http://www.rpi.edu/dept/chem/chem_faculty/profiles/pdfs/ferris/Huang_MS_JACS_2006%203.pdf</ref>
===From Ice===
Strands of RNA have been shown to form in salty ice water. David Deamer's lab at the University of California at Santa Cruz has found that the process of freezing a dilute solution of RNA nucleotides causes the nucleotides to become concentrated as ice crystals form, eventually resulting in the formation of strands of RNA. <ref>J.
