AML is a condition affecting the adult population with a median age at presentation of 67 years. AML accounts for approximately 80% of acute leukaemia diagnosed in adults . Think, for instance, of an . E. coli . cell living in the erratic environment of a human colon, dependent for its nutrients on the whimsical eating habits of its host. If the bacterium is deprived of the amino acid tryptophan, which it needs to survive, it responds by activating a metabolic pathway to make its own tryptophan from another compound. Later, if the human host eats a tryptophan-rich meal, the bacterial cell stops producing tryptophan for itself, thus saving the cell from squandering its resources to produce a substance that is available from the surrounding solution in prefabricated form. This is just one example of how bacteria tune their metabolism to changing environments.. Prokaryotes and eukaryotes precisely regulate gene expression in response to environmental conditions. In multicellular eukaryotes, gene expression regulates development and is responsible for differences in cell types. Questions to Ponder…... How do your cells “know” what kind of cell they are?. How do your cells “know” when to make a particular protein? When to stop making it?. How does the environment affect your cells?. Draw 8 boxes on your paper. Gene regulation accounts for some of the phenotypic differences between organisms with similar genes.. 2005-2006. Gene regulation in bacteria. Control of gene expression enables individual bacteria to adjust their metabolism to environmental change. ziua 1. Personaje :. Materiale necesare:. 2 şine( pt perdele) de 2m lungime..
