It is possible to distinguish chemical mutagens by their modes of action; some of these cause mutations by mechanisms similar to those which arise spontaneously while others are more like radiation (to be considered next) in their effects.

III B. CHEMICAL MUTAGENS ... Chemical mutagens are defined as those compounds that increase the frequency of some types of mutations. ... Yet another class of chemical mutagens, the so-called "ICR" compounds, induce frameshift mutations and these will be treated in the section on frameshift mutations. Some are depicted in...

A constructed pso8-1 rad4-4 double mutant was super-sensitive to UVC, thus indicating a synergistic interaction of the two mutant alleles. Molecular cloning via complementation of the pso8 mutant's sensitivity phenotype and genetic studies revealed that pso8...

Chemical Mutagens - Chemical mutagens can be divided into two classes those mutagens which can cause mutations to both replicating and non replicating DNA, are called as class I mutagens, those chemicals, which affect replicating nucleic acids are called as class II mutagens.

A test for determining if a chemical is a mutagen. Named for its developer, Bruce Ames. ... Many chemicals are not mutagenic (or carcinogenic) in themselves, but become converted into mutagens (and carcinogens) as they are metabolized by the body. This is the reason the Ames test includes a mixture of liver enzymes.
