Jacob and Monod: From Operons to EvoDevo
As Francois Jacob tells it, one afternoon in September 1958, just back from New York, he walked into Jacque Monod’s office at the Pasteur Institute in Paris; he believed he had something exciting to discuss. But he found an unimpressed Monod brusquely dismissive. Tired from his flight, Jacob quickly gave up and went home to bed. The next day he returned re-energized and found an altogether more...
متن کاملJACOB/MONOD: HOW THE REPRESSOR PROTEIN CONTROLS THE lac OPERON
The same processes that permit cellular control of metabolism also provide the means of regulating how genes are expressed. At the metabolic level, cellular compounds bind to specific enzymatic proteins, changing their shape and therefore their function. At the level of mRNA synthesis, a similar series of allosteric controls (enzymes) exists, regulating which genes are transcribed and to what e...
متن کاملSelf-Substained Oscillations in the Jacob-Monod Mode of Gene Regulation
A plausible macroscopic model of genetic regulation by feedback repression, evolved from the original formulation of Goodwin, is considered. This model has the form of a second-order non-linear dynamic system, ~ = fl(x,y), # = f2(x,y), where x(t) ~ 0 describes the mRNA which codes for the protein y(t) ~ 0, the latter acting as a repressor. Published analytical, analog, and digital studies of th...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
