Self-complementary hexanucleotides d(GGINCC) (N=C, A, G, T) were synthesized by the phosphotriester method. The circular dichroism (CD) spectra of these oligonucleotides showed that the oligonucleotides containing I : C or I : A pairs seem to possess a shape similar to deoxyribonucleic acid (DNA) with right-handed stacking.
自互补六核苷酸 d(GGINCC) (N=C, A, G, T) 通过
磷酸三酯法合成。这些寡核苷酸的圆二色性 (CD) 光谱显示,含有 I : C 或 I : A 配对的寡核苷酸似乎具有与右手叠加的
脱氧核糖核酸 (DNA) 相似的形状。
