while delayed photoreversal ( pr ) mutagenesis has been interpreted as a measure of misincorporation step in targeted mutagenesis , the specificity to produce glutamine trna suppressor mutations ( c to t transitions ) at sites in dna where a thymine-cytosine dimer ( t = c ) may target mutation suggests a deamination model : deamination t = c to t = u and trans-u dna replication after pr .
