Two questions about operon (transcription/translation)

... ideal position to start translating the next reading frame, making it unnecessary to have another RBS. This phenomenon is known as translational coupling. For #2 I honestly don't know the answer, but i think you should be able to find it via a google scholar search, seeing how it's just some ...

When are parts of prokaryotic operons seperated?

... the start codon for the downstream ORF. this arrangement circumvents the need to a RBS to recruit the ribosome. This is known as translational coupling. (from Watson et al. Molecular Biology of the gene 6th edition. page 460). it may be translational coupling that happens in the lac operon. ...

Re: SOS...please help, Na+/H+ pump problem

Well then, you know that the Na+/H+ pump works by coupling the Na+ transportation into the cell to the transportation of H+ to the extracellular fluid, and that for each atom of Na+ that it is transported across the cell, there is one H+ transported ...

The Iron Hypothesis

... which is a water nucleator i.e. a rainmaker. Unproductive areas are far from land (see above) and the most productive ones are where you have a coupling of light and nutrients from upwellings and shelves etc. The acid bit I have no idea about... I imagine some of that is wrong, but it's very ...

Mathematical Biology, metabolism, origins of life, evolution

... equation deals with metabolic rate and biomass. The term ME occurs in the exponent of biomass, and is clearly a statement of efficiency of redox coupling. This means electrochemistry. Metabolic rate is then expressed in watts, and is a statement of the needed recharge rate of an electrolytic ...
