Abstract :

The triple helix formation by the oligonucleotide (5’)d(G(4)T(4)G(4)- [T-4]-G(4)A(4)G(4)- [T-4]-C4T4C4) ([T-4] represents a stretch of 4 thymine residues) has been investigated by UV absorption spectroscopy and circular dichroism. In a 10 mM sodium cacodylate, 0.2 mM disodium EDTA (pH 7) buffer, we show : the following significant results :
