Another study in the 1990s showed that montmorillonite clay can help create RNA chains of as many as 50 nucleotides joined together spontaneously into a single RNA molecule.
Outro estudo da década de 1990 mostrou que as arxilas de montmorillonita podían axudar a crear cadeas de ARN de 50 nucleótidos que se unirían espontaneamente formando unha soa molécula de ARN.
