Differentia. sca.ning ca.orimetry (DSC) melting a.a.ysis wa. performed on 27 short double stra.ded DNa.duplexes conta.ning 15 to 25 ba.e pa.rs. Experimenta. duplexes were divided into two ca.egories conta.ning either two 5’ da.gling-ends or one 5’ a.d one 3’ da.gling-end. Duplex regions were incrementa.ly reduced from 25 to 15 ba.e pa.rs with a.concurrent increa.e in length of da.gling-ends from 1 to 10 ba.es. Blunt-ended duplexes from 15 to 25 ba.e pa.rs served a. controls. a. a.ditiona. set of molecules conta.ning 21 ba.e pa.r duplexes a.d a.single four ba.e da.gling-end were a.so exa.ined. DSC melting curves were mea.ured in va.ying concentra.ions of sodium ion (Na.). From these mea.urements, thermodyna.ic pa.a.eters for 5’ a.d 3’ da.gling-ends were eva.ua.ed a. a.function of da.gling end length. 5’ ends were found to be slightly sta.ilizing but essentia.ly consta.t while the 3’ ends were desta.ilizing with increa.ing length of the da.gling-end. 3’ ends a.so displa. a.stronger dependence on Na. concentra.ion. In lower Na. environment, the 3’ ends were more desta.ilizing tha. in higher sa.t environment suggesting a.more significa.t electrosta.ic component of the desta.ilizing intera.tions. a.a.ysis of thermodyna.ic pa.a.eters of da.gling ended duplexes a. a.function of Na. concentra.ion indica.ed the 3' da.gling ends beha.e differently tha. 5' da.gling ended a.d blunt-ended duplexes. Molecules with one 5' a.d one 3' da.gling end showed va.ia.ion in excess specific hea. ca.a.ity (ΔCp) when compa.ed to the blunt-ended molecule, while the molecules with two 5’ ends ha. ΔCp va.ues tha. were essentia.ly the sa.e a. blunt-ended duplexes. These observa.ions suggested differences exist in duplexes with 3’ a.d 5’ da.gling ends, which a.e interpreted in terms of composite differences in intera.tions with Na., solvent, a.d termina. ba.e pa.rs of the duplex.
