RESUMO
4,5',8-Trimethylpsoralen (TMP) monoadducts inactive transforming deoxyribonucleic acid (DNA) in Bacillus subtilis. Contrary to TMP diadducts (TMP cross-links), which severely inhibit entry of donor DNA (G. Venema and U. Canosi, Mol. Gen. Genet. 179:1--11), TMP monoadducts have only a slight effect on entry. Since reextracted TMP-monoadduct-containing transforming DNA is a differentially repaired by Uvr- and Uvr+ recipients and cross-linkable to the recipient strand in the heteroduplex recombinant DNA molecules, the monoadducts can be integrated along with the donor DNA into the recipient chromosome.
