Secondary Sugars(metabolism/sugar/bacteria/Lac Operon)

... but I stumbled across something that seemed to be of use; that secondary sugars might be sugars the require cAMP and CRP to be the effector of the operon(along with the operon inducer of course). Since gallactose is what the cell wants the most then the other metabolic operons(like lactose) should ...

Secondary Sugars(metabolism/sugar/bacteria/Lac Operon)

What are secondary sugars? I'm studying for the final tomorrow and we are focusing a lot on the lac operon series and some of the metabolic processes of sugars. I know that bacteria cells prefer galactose, but will still use lactose, so does that mean lactose is a secondary ...

RNA

... regulatory elements are in essence transcriptional regulators/promoter sequences that are categorized based on acting distance. The lac operon in E.coli is a typical example of a cis-acting element. Promoter sequences that regulate expression of the genes contained within the operon ...

Genetics problems

Hii!!! I was wandering if a phenotype is expressed as a consequence of 2 different genes, are these genes part of an operon or are regulated by different promoters, meaning that can be located far away? ( in a prokaryotic organisms)??
