Miss Falana, who was seen in televison commercials in a skinâtight tigerstriped costume, did Tigress commercials for two years, from 1974 through 1976. âSince then, we've used just models,â a company aide said.âNot that Lola and Tamara aren't models. It's just that they are name models.ââ¢.
The E-Z system. The problem with the cis-trans system for naming geometric isomers. Consider a simple case of geometric isomerism which we've already discussed on the previous page. You can tell which is the cis and which the trans form just by looking at them. All you really have to remember is that trans means across (as in transatlantic or transcontinental) and that cis is the opposite. It is a simple and visual way of telling the two isomers apart.
cis-regulatory elements (CREs) are regions of non-coding DNA which regulate the transcription of nearby genes. The Latin prefix cis translates to âon this sideâ. CREs are found in the vicinity of the gene, or genes, they regulate.n example of a cis-acting regulatory sequence is the operator in the lac operon. This DNA sequence is bound by the lac repressor, which, in turn, prevents transcription of the adjacent genes on the same DNA molecule.
