UV degradation of deoxyribonucleic acid

UV degradation of deoxyribonucleic acid

The effects of UV synchrotron radiation on deoxyribonucleic acid (DNA) cast films have been systematically investigated by vacuum ultraviolet and infrared spectrophotometry as a function of irradiation time. Cast DNA films exposed at 140 nm (8.85 eV) for different irradiations times, revealed consistent changes in their VUV spectra which indicate a decrease of thymine groups and an increase of ...

Initial degradation of deoxyribonucleic acid after injection in mammals.

Phleomycin-stimulated degradation of deoxyribonucleic acid in Escherichia coli.

Phleomycin stimulates the degradation of DNA by energy-dependent endonuclease and exonuclease reactions in Escherichia coli rec(+) cells and in recB(-) and recC(-) cells that lack an adenosine triphosphate-dependent nuclease functioning in the repair of ultraviolet (UV) lesions. Exonuclease activity is blocked in T4 phage-infected cells. The endonuclease reaction produces 10(7)-dalton segments ...

Deoxyribonucleic acid-deoxyribonucleic acid hybridization assay for replication origin deoxyribonucleic acid of Escherichia coli.

Deoxyribonucleic acid (DNA)-DNA hybridization on nitrocellulose filters can be used to assay for replication origin DNA from Escherichia coli if the DNA attached to the filters is enriched for the replication origin sequences. Such DNA can be readily isolated from very rapidly growing cells. When low amounts of this DNA were attached to filters, radioactively labeled DNA from the replication or...
