the rate of dna-chain elongation was studied in mouse fm3a cells after treatment with 8-methoxypsoralen plus near-ultraviolet radiation using the minimal doses ( 1 microgram/ml 8-methoxypsoralen plus 1-2.5 kj/m2 of near-ultraviolet radiation ) which inhibited cell-cycle progression or dna replication .
