We investigated the structural shape transitions induced in the QII ( G ) phase upon complexation with a series of sDNAs ( 5 , 11 , 24 , and 48 bp ) with three types of end structure ( " sticky " adenine ( A ) - thymine ( T ) ( dAdT ) overhangs , no overhang ( blunt ) , and " nonsticky " dTdT overhangs ) using synchrotron small - angle X - ray scattering .
