abstract：:The CD spectra of twelve DNA restriction fragments ranging in size from 12 to 360 base pairs are reported. Since the sequences of these fragments are known, it is possible to calculate their CD spectra from a set of nearest neighbor contributions derived from a combination of synthetic polydeoxyribonucleotides. While ...
