Carlill v Carbolic Smoke Ball Co your clothes whiter than white!"). Secondly, although it was not discussed in the case, there was evidence at the time that using the smoke ball actually made people more vulnerable to the flu (carbolic acid was put on the poisons register in 1900). The General Product Safety Regulations which are part of a European Union wide consumer protection regime (Directive 2001/95/EC) again provide criminal penalties for unsafe products. Thirdly, the Consumer Protection Act 1987 (which is also part of EU wide regulation under Directive 85/374/EEC) creates a statutory tort of strict liability for defective products that cause any kind of
Xeno nucleic acid Xeno nucleic acid Xeno nucleic acid (XNA) is a synthetic alternative to the natural nucleic acids DNA and RNA as information-storing biopolymers that differs in the sugar backbone. As of 2011, at least six types of synthetic sugars have been shown to form nucleic acid backbones that can store and retrieve genetic information. Research is now being done to create synthetic polymerases to transform XNA. The study of its production and application has created a field known as xenobiology. Although the genetic information is still stored in the four canonical base pairs (unlike other nucleic acid analogues), natural DNA polymerases
