Poly(dA).poly(dT) has unusual properties in that it cannot associate into | Poly(dA).poly(dT) has unusual properties in that it cannot associate into nucleosomes and short, phased runs of it cause DNA bending. The crystal structure of a B-type DNA dodecamer containing a homopolymeric run of six A.T base pairs shows that this region possesses special structural features, including a system of bifurcated hydrogen bonds, which explains some of the properties of this simple homopolymer. | ||
