Repetitive DNA sequences exhibit complex structural and energy landscapes, populated by metastable, non-canonical states, that favor expansion and deletion events correlated with disease phenotypes. To probe the origins of such genotype-phenotype lin

Clusters of closely spaced oxidative DNA lesions present challenges to the cellular repair machinery. When located in opposing strands, base excision repair (BER) of such lesions can lead to double strand DNA breaks (DSB). Activation of BER and DSB r

Biopolymers exhibit rough energy landscapes, thereby allowing biological processes to access a broad range of kinetic and thermodynamic states. In contrast to proteins, the energy landscapes of nucleic acids have been the subject of relatively few ex

Cytosine-rich DNA at low pH adopts an antiparallel tetraplex structure via the intercalation of two partially protonated, parallel stranded duplexes. This intriguing structural motif has been named i-DNA. We have used a combination of spectroscopic a

Trinucleotide repeats are involved in a number of debilitating diseases such as myotonic dystrophy. Twelve to seventy-five base-long (CTG)n oligodeoxynucleotides were analysed using a combination of biophysical [UV-absorbance, circular dichroism and

The effects of various protoporphyrinogen oxidase (PPOX) mutations responsible for variegate porphyria (VP), the roles of the arginine-59 residue and the glycines in the conserved flavin binding site, in catalysis and/or cofactor binding, were examin

The melting temperature of the poly(dA)·poly(dT) double helix is exquisitely sensitive to salt concentration, and the helix-to-coil transition is sharp. Modern calorimetric instrumentation allows this transition to be detected and characterized with

Energy coupling between distal DNA domains, may have profound regulatory consequences for biological processes, allowing for allosteric control of nucleic acid function. Repair of oxidative lesions at or near triplet repeat domains can enhance DNA ex
