Advances in Mutagenesis Research (eBook, PDF)

Redaktion: Obe, Günter

• Format: PDF

Produktbeschreibung

Applied genetic research, genetic toxicology and mutation research investigate the mutagenicity and cancerogenicity of chemicals and other agents. Permanent mutation in genes and chromosomes, can be induced by a plethora of agents, including ionizing and nonionizing radiations, chemicals, and viruses. Among the aspects discussed by Advances in Mutagenesis Research are (1) the understanding of the molecular mechanisms leading to mutations, and (2) the prevention of a thoughtless introduction of mutagenic agents into the environment.
