Aim To improve the synthetic procedure of bromomethyl cyclobutane. 目的改进溴甲基环丁烷的合成方法。
Cyclobutane exists predominantly in a "butterfly" conformation, in which the dihedral angle between the two wings is about 20°. 环丁烷主要成“蝶式”构象存在,其中两翼间的二面角大约为20°。
UV-B-induced cyclobutane pyrimidine dimmers (CPD) in the DNA of rice seedlings were measured using ELISA with specific monoclonal antibody. 摘要采用单克隆抗ELISA检测了UV-B对水稻叶片CPD的诱导形成及温度的影响。
In this paper, recent progresses in model studies of cyclobutane pyrimidine dimer photolyases and (6-4) photoproduct photolyases have been reviewed. 评述了环丁烷型嘧啶二聚体光解酶和(6-4)光产物光解酶的模型研究进展,并展望了该领域的发展前景。
