The crystal structure of thymine monohydrate
TL;DR: In this article, the crystal structure was refined on the basis of three-dimensional intensity data obtained with copper radiation, and the structural parameters for the heavy atoms, including anisotropic temperature factors, were refined by the least-squares method; the positions of the hydrogen atoms were located from a threedimensional difference synthesis.

Transmission of stability (telestability) in deoxyribonucleic acid. Physical and enzymatic studies on the duplex block polymer d(C15A15) - d(T15G15).
TL;DR: The properties of the duplex block polymer d(C15A15) - d(T15G15) were examined by thermal denaturation and nuclease susceptibility studies and the nucleotide composition of one region of this synthetic double-helical DNA affected the properties of a contiguous but remote region.
