The restriction endonuclease Alu I induces chromosomal aberrations in living Chinese hamster ovary (CHO) cells. Multiple fixation times reveal that the chromosome-breaking activity of Alu I is similar to that of ionizing radiation in that it is independent of the S-phase of the cell cycle. These results indicate that DNA double-strand breaks are the ultimate lesions for the production of chromosomal aberrations in all stages of the cell cycle.
限制性内切酶Alu I可诱导活的中国仓鼠卵巢(CHO)细胞发生染色体畸变。多次固定时间的结果表明,Alu I的染色体断裂活性与电离辐射相似,即它与细胞周期的S期无关。这些结果表明,DNA双链断裂是细胞周期所有阶段产生染色体畸变的最终损伤。
