Abstract
- Non-enzymatic RNA replication may have been one of the processes involved in the appearance of life on Earth. Attempts to recreate this process in a laboratory setting have not been successful thus far, highlighting a critical need for finding prebiotic conditions that increase the rate and the yield. Now a highly parallel assay for template directed RNA synthesis is presented that relies on the intrinsic fluorescence of a 2-aminopurine modified G-quadruplex. The application of the assay to examine the combined influence of multiple variables including pH, divalent metal concentrations and ribonucleotide concentrations on the copying of RNA sequences is demonstrated. The assay enables a direct survey of physical and chemical conditions, potentially prebiotic, which could enable the chemical replication of RNA.<br /> (© 2018 Wiley-VCH Verlag GmbH & Co.
