— A haploid respiration‐deficient (ρ ‐ ) mutant of Saccharomyces cerevisiae exhibits a lower ability to excise ultraviolet‐induced pyrimidine dimers in various post‐irradiation treatments as compared to the original respiration‐competent wild‐type strain. This decrease in excision may account for the inability of ρ ‐ strains to show liquid‐holding recovery.
