Following PAGE purification, strands for the seeds, daughter and granddaughter tiles were mixed stoichiometrically as estimated by OD 260
and dissolved to 0.5 μM in TAE/Mg 2+
buffer (40 mM Tris-HCl, 20 mM Acetic Acid, 2 mM EDTA, 12.5 mM Magnesium Acetate, pH 8.0). The solutions were slowly annealed from 90 °C to room temperature (RT) over 48 hours in a 2-litre water bath insulated in a Styrofoam box. Stoichiometric quantities of seven seed tiles were mixed and annealed from 45 °C to RT over 24 hours to make seeds. To form the first generation, three first-generation tiles (I′, A′, and B′😉 were mixed with annealed first-generation tiles (seeds:I′:A′:B′=1:2:4:8), and slowly annealed from 45 °C to RT. Dynabeads were washed with ddH

Dynabeads were washed with ddH
O and TAE/Mg buffer, mixed with beads linker in TAE/Mg buffer, slowly annealed from 55 °C to RT, washed with buffer, and mixed with DNA solution. The solution containing dynabeads was annealed from 33 °C to 23 °, placed on a magnetic stand and washed with TAE/Mg buffer. Linking strands 2, 6 and 9 were then added, the solution cooled from 33 °C to 23 °C, placed on a magnetic stand and washed with TAE/Mg buffer to remove excess linkers. Dynabeads in TAE/Mg buffer were kept at 37 °C for one hour, placed on the magnetic stand, and the solution was removed from dynabeads and stored in a clean tube for AFM imaging. Formation of the second generation is similar to the first: It starts from initial seed preparation, followed by formation of the first generation, and adding second-generation tiles (I″, A″, and B″😉. Steps (2)-(8) described in formation of the first-generation were repeated."
This solution would never occur outside of a lab let alone persist for millions of years.
They pre-built portions of the RNA molecule and placed them in the solution. So it didn't have to build itself bit by bit it did it chunk by chunk. I forgot about that bit, I was going under the impression that they had all the nucleotides in solution with nothing else. It's much much more designed than I thought. Then you have all the rinsing and removing of "linkers". LOL
