We have determined the crystal structure of a four-way DNA junction by multiwavelength anomalous diffraction, and refined it to 2.16 Å resolution. The structure has two-fold symmetry, with ...

This means that one strand's sugar-phosphate chain runs in ... Crick were pursuing a definitive model for the stable structure of DNA inside cell nuclei. Watson and Crick ultimately used ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double ... The double helix unwinds, and ...
