The influence of the oxidative lesion 2'-deoxy-7-hydro-8-oxoguanosine (8-oxodG) on some conformational properties of DNA has been studied. Four 30-mer duplexes of the form [5'-GATCCTCTAGAGTC[G(*) or G]ACCTGCAGGCATGCA-3']:[3'-CTAGGAGATCTCAG[C or A]TGG

This study is aimed at comparing the radiosensitivity of a 21-mer DNA fragment in duplex and triplex form (Py x Pu duplex and Py x Pu:Py triplex) and to give insights into the fine structural features due to the different strandedness.The triplex sam

The conformational response of calf thymus DNA to solvent conditions altered by varying amounts of ethanol, 2-propanol and tert-butanol has been monitored by circular dichroism. These measurements reveal above a critical cosolvent mole fraction x 2

In this paper, we report dielectric spectroscopy and optical measurements on lysozyme in water-ethanol mixtures as a function of alcohol concentration in the water-rich region of composition (cosolvent mole fraction X ⩽0.25). Dielectric measurement

We have studied the torsional elastic constant (alpha) of short DNA (27mer) oligomers of various sequence by fluorescence polarization anysotropy (FPA) measurements. The lowest alpha values were found in samples with sequence rich in AA dinucleotides

A 27-mer sequence was synthesised as DNA duplex (DD), RNA duplex (RR), and RNA-DNA (RD) hybrid in order to characterise their structural and dynamic features. The hydrodynamic radius (Rh) and the rise (b) values of the three samples were consistent w

We compared the structural and dynamical properties of two DNA fragments, 27 bp long, having the same base composition but a different sequence. This work aims to understand how the base sequence on a purine rich strand in a double helix, which is im

The thermodynamic and dielectric properties of a 21 base pair DNA have been evaluated and compared with those of samples with some defects. In particular, fragments in which the absence of a phosphate group (nick) or of two nucleotides (gap) causes c

— When DNA is complexed with Cu2+ ions it becomes sensitized to mid-UV light. Irradiation of the complex at 310 ± 10 nm produces marked changes in absorption and circular dichroism spectra in addition to those in melting profiles of irradiated sam
