The new field of applied genetic research, genetic toxicology and mutation research investigates the mutagenicity and cancerogenicity of chemicals and other agents. Permanent changes in genes and chromosomes, or genome mutations, can be induced by a plethora of agents, including ionizing and nonionizing radiations, chemicals, and viruses. Mutagenesis research has two aims: (1) to understand the molecular mechanisms leading to mutations, and (2) to prevent a thoughtless introduction of mutagenic agents into our environment. Both aspects, namely, basic and applied, will be treated in the new...

Chromosomale Mutationen sind eine der m-glichen Ursachen f}r Ver{nderungen der Erbinformation. Neben grunds{tzlichen As- pekten, wie Reparaturmechanismen der Zelle oder Ursachen von Chromosomenver{nderungen, werden angewandte Aspekte, z.B. Chromosomen als Testindikatoren der Toxizit{t, behandelt.

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.

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.

Due to sensitive molecular biological techniques, our understanding of chromosomal aberrations is steadily increasing. Provided here is a review of basic and applied aspects of the field. Chromosome structure, induction of DNA lesions by different clastogenic agents and their repair, induction of aberrations by agents which affect specific sequences in the DNA, and factors affecting induction and yield of chromosomal aberrations are covered.
Further, topics such as automation of aberration scoring, problems associated with using chromosomal aberrations and micronuclei in population...
