The price for simplicity of the linear genetic code is the inevitably large size of genomes and the attendant DNA entanglements. Circular chromosomes, or closed circular chromosome domains, are prone to knotting and catenation by a variety of DNA transactions. Knots in DNA pose road blocks to replication and transcription and increase the frequency of genetic rearrangements (1). Topoisomerases,...

A new set of [Cu(phen)2]+ based rotaxanes, featuring [60]-fullerene as an electron acceptor and a variety of electron donating moieties, namely zinc porphyrin (ZnP), zinc phthalocyanine (ZnPc) and ferrocene (Fc), has been synthesized and fully characterized with respect to electrochemical and photophysical properties. The assembly of the rotaxanes has been achieved using a slight variation of o...

Our discovery of human papillomavirus type 47 (HPV47) in benign lesions from a patient suffering from epidermodysplasia verruciformis prompted us to examine whether the viral DNA also resided in malignant lesions from the same patient. By using newly devised protocols for amplifying a group of epidermodysplasia verruciformis-associated HPV DNAs by PCR and differentially identifying them by reve...
