- The Eurobarometer on Biotechnology (46.1) was conducted during October and November 1996. The survey conducted in each EU (European Union) country used a multi-stage random sampling procedure and provided a statistically representative sample of national residents aged 15 and over. The total sample within the EU was 16,246 respondents (about 1,000 per EU country). The survey questionnaire was designed by the authors as part of a larger study involving the comparative analysis of public perceptions, media coverage and public policy in relation to biotechnology from 1973 to the present.

DNA-LIKE DOUBLE HELIX FORMED BY PEPTIDE NUCLEIC-ACID
- 1994

- ALTHOUGH the importance of the nucleobases in the DNA double helix is well understood, the evolutionary significance of the deoxyribose phosphate backbone and the contribution of this chemical entity to the overall helical structure and stability of the double helix is not so clear. Peptide nucleic acid (PNA)1-7 is a DNA analogue with a backbone consisting of N-(2-aminoethyl)glycine units (Fig. 1) which has been shown to mimic DNA in forming Watson-Crick complementary duplexes with normal DNA7. Using circular dichroism spectroscopy we show here that two complementary PNA strands can hybridize to one another to form a helical duplex. There is a seeding of preferred chirality which is induced by the presence of an L- (or D-) lysine residue attached at the carboxy terminus of the PNA strand. These results indicate that a (deoxy)ribose phosphate backbone is not an essential requirement for the formation of double helical DNA-like structures in solution.
