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 ...

Structure: DNA is composed of two long chains of nucleotides forming a double helix. The nucleotides within each strand are joined together through covalent (specifically phosphodiester) bonds between ...

Of course, though, testing a child's parentage based on physical features is far too subjective — that's typically where DNA tests come in. Such tests can offer a far more scientific way of ...
