Other claims from this paper (8)

Intervention effect Mitomycin C significantly increased X-ray-induced chromosome aberrations.
Intervention effect chloramphenicol significantly increased X-ray-induced chromosome aberrations.
Intervention effect ATP reduced chromosome aberration yield.
Intervention effect The DNA base component nucleoside mixture significantly decreased aberration yield.
Intervention effect Four RNA component nucleosides did not significantly reduce aberration frequency, although a reduction tendency was seen.
Intervention effect Mitomycin C completely arrested the favorable action of the nucleoside mixture and ATP on chromosome break rejoining.
Intervention effect Chloramphenicol completely arrested the favorable action of the nucleoside mixture and ATP on chromosome break rejoining.
Mechanism The authors suggest DNA and protein syntheses are involved in rejoining X-ray-induced chromosome breaks.
