Advances in Mutagenesis Research

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 aplethora of agents, including ionizing and nonionizing§radiations, chemicals, and viruses.§Among the aspects discused 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.§Contents: Nikolay W.
