In which phase of cell cycle does  stress-induced transcription-associated mutagenesis (TAM) occur?
['factors involved in RNA polymerase (RNAP) processivity or transcriptional derepression contribute to the generation of stress-induced mutations. In Bacillus subtilis, transcription-associated mutagenesis has been shown to be independent of recombination-dependent repair and, in some cases, of the Y DNA polymerases. Central to stationary-phase mutagenesis in B. subtilis is the requirement for Mfd, transcription coupling repair factor', 'Adaptive (stationary phase) mutagenesis is a phenomenon by which nondividing cells acquire beneficial mutations as a response to stress.', 'the level of Leu(+) reversions increased significantly in parallel with the induced increase in transcription levels. This mutagenic response was not observed under conditions of exponential growth. Since transcription is a ubiquitous biological process, transcription-associated mutagenesis may influence evolutionary processes in all organisms.', 'Transcription-associated mutation in Bacillus subtilis cells under stress.', 'Transcription-associated mutagenesis is increased under stress and depends on the DNA sequence.', 'Nonrandom transcription-associated mutagenesis under stress should improve the survival of E.', 'Transcription-associated mutagenesis is increased under stress and depends on the DNA sequence.', 'Stress-induced mutagenesis describes the accumulation of mutations that occur in nongrowing cells, in contrast to mutagenesis that occurs in actively dividing populations, and has been referred to as stationary-phase or adaptive mutagenesis.', 'Central to stationary-phase mutagenesis in B']
