cisandtransepigeneticsignals “Transepigeneticsignal”在细胞分裂的过程中通过胞质的分配而得以传递,这种信号是通过转录因子形成的反馈环和网络维持的,例如,能够激活自身转录的转录因子,能够形成一种表观遗传信号,并且这种信号(转录因子)能够在不存在外界刺激的情况下通过胞质的分配而得以传递,并且这种遗传的转录因子...
structures of cis-Mo(CO)(4)(5), 10, and cis-Mo(CO)(4)(9), 12, have been determined by single-crystal X-ray methods and reveal significant differences between the two forms, most notably in the chelate bite angle which is 100.68(18)degrees in 10 compared to 88.12(2)degrees in 12...
Hey, I am confused as to why the following two pairs of molecules are cis and trans isomers. The answers in the solutions manual say they are cis and trans isomers. To me, the first pair seems like the same molecule. Besides the double bond that is there, the rest of the bonds are ...

Stereoselective synthesis of methyl (1R) trans- and (1R) cis-hemicaronaldehydes from natural tartaric acid: Application to the synthesis of s-bioallethrin ... A novel process for the preparation of compounds of the formula ##STR1## with cis or trans structure in racemic or optically active...
The chemistry of the highly strained cis,trans-cyclo-octa- 1,5-diene ring system* (1) is largely unexplored. Because there is a possibility that the corresponding 3,4-dimethyl derivatives 2 and 3 may be involved in the thermal nonboat, "... JA Berson,PB Dervan,JA Jenkins - 《Journal...
Gene transfer experiments using estrogen-responsive cells have shown that the 13 bp perfect palindromic element GGTCACTGTGACC found upstream of the Xenopus laevis vitellogenin gene A2 promoter mediates hormonal stimulation and thus, was called the estrogen-responsive element (ERE). In the Xenopus ...
In contrast, cis-zeatin is commonly regarded as a cytokinin exhibiting low or no activity. Here we comparatively study the impact of both zeatin isomers on the infection of Nicotiana tabacum by the (hemi)biotrophic microbial pathogen Pseudomonas syringae. We demonstrate a biological effect of cis-...
(+)-cis-Sabinene hydrate and (+)-trans-sabinene hydrate are the main monoterpenes found in marjoram (Origanum majorana), but can also be found in other Origanum species as well, as in e.g. Melaleuca alternifolia. The synthesis of sabinene hydrate in marjoram (Origanum majorana) is performed...
