Abstract

Monomeric products of the 5,6-dihydroxy-dihydrothymine type are produced in the DNA by both ultraviolet and ionizing radiations. The capacity of nuclear preparations from normal and Xeroderma pigmentosum (XP) cells (Complementation groups A, B, C and D) to excise such products from ultraviolet or gamma-irradiated T7DNA was comparable and was independent of radiation induced strand breaks.

摘要

5,6 - 二羟基 - 二氢胸腺嘧啶类型的单体产物可由紫外线和电离辐射在DNA中产生。来自正常细胞和着色性干皮病（XP）细胞（互补组A、B、C和D）的核提取物从紫外线或γ射线照射的T7DNA中切除此类产物的能力相当，且与辐射诱导的链断裂无关。
