Structural transitions in polyadenylic acid and hypothesis on biological role of its double-stranded forms.

Abstract

Under various conditions poly(A) exists in different forms such as single-stranded helix, two double-helical forms and others. The formation of double-stranded helices is induced by adenine protonation. Under physiological ionic strengths they are formed at acidic pH, but under the same conditions methylated poly(A) has double-stranded structure at alkaline… (More)
