Document Summary
Lecture xv regulation of bacterial cellular processes. How do cells decide to express one set of genes over another and why that"s important. Interactions between -omes : even though we"re going to be talking about individual genes, and isolated topics, Iv. those are just examples out of many things: many things have to be synthesized; and many things have to be regulated, when we think about e. coli (lab workhorse), it"s incredibly common; has about. In central molecular biology dogma, the transfer of information can be regulated in each step; if multiple steps in a given process, (initiation, elongation, termination), each one of those substeps can be regulated. Arabinose operon: can feed into glycolysis; like lactose, when not present, the product of the regular gene binds to dna and makes a big loop, rna pol, presence of arabinose activates operon.
