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...
If we go back to our cis/trans practice problems, such as cis and trans 2-butene, you’ll see that we can use the E/Z system here as well. Carbon 2 and 3 each have a methyl group outranking a hydrogen atom. When they are cis, you get Z. When they are trans you get E. A ...

Conditions are studied for the conversion of cis-quinonedichloride into the trans-isomer and subsequently into 2,3-dichloroquinol. The course of the reaction between sulphuryl chloride and quinol is elucidated.doi:10.1002/recl.19540730102A. P. ter Borg...
"has cis / trans been replaced with E/Z" was it? (3) IUPAC does in fact discourage the use of "cis" and "trans" in favor of E-Z in their preferred names see "Nomenclature of Organic Chemistry: IUPAC Recommendations and Preferred Names, 2013" by ...
I understand problem e now, but I am still confused about g. I have not learned E-Z yet, so cis- and trans- is all I have. I am just beginning Orgo, so I am sorry for sounding stupid and not knowing all the correct terms for everything. ...
Configurational isomerization of cis - and trans -1,2-, 1,3-, and 1,4-dimethylcyclohexanes has been studied on Rh/SiO 2 catalyst in the range of 373–523 K and a hydrogen partial pressure range of 13.3–100 kPa. Temperature has a small effect on the isomerization rate while this rate...

In isomerism: Cis and trans forms The examples presented so far have concentrated on the simplest organic molecules, the alkanes. However, stereoisomers crop up in many of the other structural types of organic chemistry. For example, in the alkenes, two versions of 2-butene exist. They are ...
