'''THE STRUCTURE OF AN OLIGO(DA).OLIGO(DT) TRACT AND ITS BIOLOGICAL IMPLICATIONS'''<br />


==Overview==
==THE STRUCTURE OF AN OLIGO(DA).OLIGO(DT) TRACT AND ITS BIOLOGICAL IMPLICATIONS==
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.
