Stabilities of nearest‐neighbor doublets in double‐helical DNA determined by fitting calculated melting profiles to observed profiles
Abstract
Melting profiles were calculated for restriction fragments of ϕX174 and fd phage DNAs and compared with experimental profiles. The algorithm of Fixman and Freire was slightly modified so that a stability parameter was assigned not to a base pair but to each nearest‐neighbor doublet. Stabilities of the 10 kinds of nearest‐neighbor doublets were estimated by fitting the calculated profiles to the observed ones. Agreement of the calculated and observed profiles was much improved by this modification. The most interesting finding was that purine (3′‐5′) pyrimidine stackings are much more stable than their respective reverses. The order of nearest‐neighbor stabilities is in excellent agreement with that of negative stacking energies calculated by Rein and coworkers by a quantum‐chemical method.

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.
