In order to study how the single rDNA copy takes the role of the double rDNA copies and the function of the inverted repeat, we cloned the 16s rRNA and its leader sequences from Brassic napus and Vicia faba chloroplasts, by using E.

由于rDNA位于反向重复顺序内，所以有反向重复顺序类型的每一个DNA分子上有两个rDNA拷贝，而无反向重复顺序类型的只有一个rDNA拷贝。

In the present study,in order to explore the roles of estrogen and progestin in epilepsy and elucidate their mechanisms of action, we utilized animal seizure models induced by intracerebroventricular coriaria lactone and intraperitoneal bemegride, studied the effects of estrogen and progestin on central nervous system functions in behavior,electrophysiological,cellular,molecular and gene levels by means of neuroelectrophysiology, flow cytometry, high performance liquid chromatography, immunocytochemical and in situ hybridization techniques.
