The spontaneous mutation rate could be increased in experimental animals by exposure to mutagens, but this was a random and undirected process. Despite the importance of mutagen-transposon interactions and the attention it has been given, the actual mechanisms occurring have only been speculated upon. This could obviously increase the duration of their exposure to mutagens. This observation may have important implications when hobo elements are used as insertional mutagens or tagging genes. The experiment was extended to include tetraploids, which, if masking increases tolerance to deleterious mutations, would be predicted to be least affected by the mutagen but to recover most slowly. Thus, while our data suggest that masking may have contributed to the increased tolerance of the higher ploidy levels to mutagens, other factors may have contributed to the observed effects. The accumulation of mutations in the viral genome can be enhanced through bottleneck events, such as those occurring during plaque-to-plaque transfers, or through the use of mutagens. Seventeen studies have been submitted, and it is now beyond scientific doubt that the mutagen 17-beta-ostradiol is genotoxic and carcinogenic. From Europarl Parallel Corpus - English It is important that we have effective binding limits for carcinogens, mutagens and substances toxic for reproduction. From Europarl Parallel Corpus - English Carcinogens, mutagens and reproduction toxins which are banned in cosmetics are permitted in toys. From Europarl Parallel Corpus - English There are a number of different classification systems for mutagens, carcinogens and allergens. From the Hansard archive Example from the Hansard archive.

Contains Parliamentary information licensed under the Open Parliament Licence v3.0 It is known that oxidised cholesterol is a mutagen and plaque tumour initiator. From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 These peroxidised fats, since they are mutagens and carcinogens, are able to initiate plaque formation. From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 I support the extension of the existing directive on carcinogens to include dust from oak and beech wood, category 1 and category 2 mutagens and vinyl chloride monomer. From Europarl Parallel Corpus - English I am, for example, pleased that we adopted an amendment to the effect that paints and varnishes should not contain substances classified as carcinogens, mutagens or substances toxic to reproduction. From Europarl Parallel Corpus - English It is also a known mutagen. From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 Currently, a large number of new, so-called "permanent" hair dyes are under suspicion as bacterial mutagens; that is to say, they induct the formation of new species of bacteria.
