Abstract excerpt
We utilized a shuttle vector plasmid (pLSC) to assess the role of DNA sequence and mismatch repair on mutagenesis in human cells. pLSC contains an interrupted 29 bp mononucleotide poly(G) run within a bacterial suppressor tRNA gene, which acts as a highly sensitive mutagenic target for detection of base substitution and frameshift mutations. The frequency of spontaneous mutations in pLSC was found to be similar...
