Non-enzymatic template-directed synthesis on RNA random copolymers

Joyce, G.F., Inoue, T., Orgel, L.E.·1984·Journal of Molecular Biology

Abstract

Poly(C, U) random copolymer templates direct the oligomerization of 2-MeImpG and 2-MeImpA, resulting in the production of a variety of oligo/(G,A)s. The efficiency of monomer incorporation into newly synthesized oligomers is greater for 2-MeImpG than for 2-MeImpA, and decreases for both monomers as the uracil content of the template increases. The relatively poor incorporation of adenine is partly due to an intrinsically less efficient incorporation reaction, and partly due to the masking of uracil sites by G X U non-complementary pairing. The efficiency of adenine incorporation can be improved by decreasing the concentration of 2-MeImpG and increasing the concentration of 2-MeImpA in the reaction mixture. The oligomeric product distribution can be characterized in detail using high-pressure liquid chromatography on an RPC-5 column. Oligomers are separated on the basis of chain length, base composition, and phospho-diester-linkage isomerism. The 3'----5' regiospecificity of monomer addition to template-bound oligomers is lower for 2-MeImpA than for 2-MeImpG. The presence of an adenine residue at the 2'(3') terminus of the acceptor strand lowers the regiospecificity of 2-MeImpA addition even further.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
