Abstract

DNA-specific labelling in Saccharomyces cerevisiae in vivo is possible with 5′-dTMP only (Jannsen et al., 1968; Brendel and Haynes, 1973; Fäth and Brendel, 1974). Thymine and thymidine cannot be used for DNA-specific labelling, because thymidine kinase apparently is absent in this organism (Grivell and Jackson, 1968). The introduction of a genetic (Fäth et al., 1974; Brendel and Fäth, 1974) or the use of a phenotypic block of thymidylate biosynthesis (Jannsen et al., 1973; Laskowski and Lehmann-Brauns, 1973) yielded a selective system for the isolation of 5′-dTMP low-requiring mutants, some of which show utilization (incorporation into DNA) of exogenously offered 5′-dTMP of between 25 and 50 per cent (Fäth and Brendel, 1975).
