Aim To improve the synthetic procedure of bromomethyl cyclobutane. 目的改進溴甲基環(huán)丁烷的合成方法。

Cyclobutane exists predominantly in a "butterfly" conformation, in which the dihedral angle between the two wings is about 20°. 環(huán)丁烷主要成“蝶式”構(gòu)象存在，其中兩翼間的二面角大約為20°。

UV-B-induced cyclobutane pyrimidine dimmers (CPD) in the DNA of rice seedlings were measured using ELISA with specific monoclonal antibody. 摘要采用單克隆抗ELISA檢測了UV-B對水稻葉片CPD的誘導(dǎo)形成及溫度的影響。

In this paper, recent progresses in model studies of cyclobutane pyrimidine dimer photolyases and (6-4) photoproduct photolyases have been reviewed. 評述了環(huán)丁烷型嘧啶二聚體光解酶和(6-4)光產(chǎn)物光解酶的模型研究進展，并展望了該領(lǐng)域的發(fā)展前景。
