the induction of genetic effects was studied in a diploid strain of saccharomyces cerevisiae ( d7 ) after treatments with the monofunctional furocoumarins 7-methylpyrido [ 3,4-c ] psoralen ( mepyps ) , pyrido [ 3,4-c ] psoralen ( pyps ) and 3-carbethoxypsoralen ( 3-cps ) and the bifunctional furocoumarins 5-methoxypsoralen ( 5-mop ) and 8-methoxypsoralen ( 8-mop ) in the presence of 365-nm radiation .
