Abstract

The thermodynamic parameters (delta H degree, delta S degree, and delta G degree 37) for 16 nearest-neighbor sets and one initiation factor are presented here in order to predict stability of RNA/DNA hybrid duplexes. To determine the nearest-neighbor parameters, thermodynamics for 68 different hybrid sequences (136 single-stranded oligonucleotides) with 5-13 nucleotide length including several duplexes with identical nearest-neighbors were measured by UV melting procedure. These sequences were selected to have many different combinations of nearest-neighbor pairs, and so that the number of the 16 nearest-neighbor sequences in the oligomers were as equal as possible. The structures of the hybrids were also investigated by measuring circular dichroism spectra. Comparing delta G degree 37 values of the hybrids with DNA/DNA and RNA/RNA parameters reported previously (Breslauer, K.J., Frank, R., Blöcker, H., & Marky, L.A. (1986) Proc. Natl. Acad. Sci. U.S.A. 83, 3746-3750; Freier, S.M., Kierzek, R., Jaeger, J.A., Sugimoto, N., Caruthers, M.H., Neilson, T., & Turner, D.H. (1986) Proc. Natl. Acad. Sci. U.S.A. 83, 9373-9377), RNA/RNA double helix is the most stable of the three kinds of helixes with the same nearest-neighbor sequences. Which is more stable between DNA/DNA and RNA/DNA hybrid duplexes depends on its sequence. Calculated thermodynamic values of hybrid formation with the present parameters reproduce the experimental values within reasonable errors.

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.
