DNA recombination is a universal biological event responsible both for the generation of genetic diversity and for the maintenance of genome integrity. A four-way DNA junction, also termed Holliday junction, is the key intermediate in nearly all recombin

In biology, "double helix" is a term used to describe the structure ofDNA. A DNA double helix consists of two spiral chains of deoxyribonucleic acid. The shape is similar to that of a spiral staircase. DNA is anucleic acidcomposed of nitrogenous bases (adenine, cytosine, guanine, and thymi...

Detailed examination of the structure of the B-DNA dodecamer C-G-C-G-A-A-T-T-C-G-C-G, obtained by single-crystal X-ray analysis (Drew et al., 1981), reveals that the local helix parameters, twist, tilt and roll, are much more strongly influenced by base sequence than by crystal...
However, the presence of two kinks causes a divergence from a straight helix. The observed deformation, which is stabilized by a few hydrogen bonds in the crystal packing, could be due to the relatively high (35 °C) temperature of crystallization. The complete analysis of the structure is ...

Biophysical and structural analysis revealed that 5fC alters the structure of the DNA double helix and leads to a conformation unique among known DNA structures including those comprising other cytosine modifications. The 1.4-Å-resolution X-ray crystal structure of a DNA dodecamer comprising three ...
Solution structure of the ETS domain from murine Ets-1: a winged helix-turn-helix DNA binding motif. Ets-1 is the prototypic member of the ets family of transcription factors. This family is characterized by the conserved ETS domain that mediates specific ... LW Donaldson,JM Petersen,BJ Grav...
The solution structure of the DNA analogue of the unusually stable r[C(UUCG)G] RNA hairpin, 5'-d[GGA-C(TTCG)GTCC]-3', has been determined by NMR spectroscopy, and its structure has been compared to that of the RNA molecule. The RNA molecule is compact and rigid with a highly stru...
