Helix formation by dAT oligomers. I. Hairpin and straight-chain helices.
TL;DR: Molecular weight measurements demonstrate that the two-chain helices are first converted into one-chain helixes at low temperatures, and then these melt at higher temperatures, which appears to be the conversion of hairpin to straight- chain helices by chain slippage.

Helix formation by d(TA) oligomers
TL;DR: There is a simple approximation by which electrostatic effects may be taken into account while retaining much of the formalism of standard helix-coil transition theory, and the melting curves can be predicted in a straightforward manner using this approximation and they agree with the experimental curves.

Thermodynamics of the helix-coil transition of the alternating copolymer of deoxyadenylic acid and deoxythymidylic acid☆
TL;DR: The method of differential heat capacity calorimetry is applied to the study of the helix-coil transition of the alternating copolymer of deoxyadenylic acid and deoxythymidylic acid, poly (dAT).

TL;DR: The results show that for small DNA loops the loop-weighting function differs from that predicted by Jacobson & Stockmayer (1950) for long gaussian chains; the differences are of the type expected for short chains with hindered rotation.
