The kinds of mutations induced by 3-chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone (MX) in the protein coding region of the hprt gene of Chinese hamster ovary (CHO) cells were determined by direct sequencing of polymerase chain reaction (PCR)-amplified cDNA. Primary mutations were found in 15 of 19 of the mutants: 11 were G:C--&gt;T:A transversions, two were A:T--&gt;T:A transversions and two were deletions of single G:C base pairs (-1 frameshifts). The remaining four mutants had large alterations in the cDNA that were explained by mRNA splicing errors. A group of control mutants had more diverse hprt cDNA alterations than MX-induced mutants. Transversions yielding an A:T base pair were the predominant type of MX-induced mutations, in agreement with previous findings in bacteria. This specificity may be explained by the 'A rule', that DNA polymerases preferentially insert adenine nucleotides opposite non-instructional lesions.
