in which you describe/evaluate how the production possibility curve helps to illustrate fundamental economic concepts. In this essay‚ I am going to evaluate the second important fragment of economics- Production possibility curve or simply PPF. The importance of understanding the method and analysing elementary economic diagrams is significant for progressing into more depth and other essential parts of the learning of economics. The starting point in economics is to measure what we

bacteria low in C&G (which are hard to transform with traditional means) by conjugation with other bacteria. Current vectors have the malR regulatory protein which imposes a problem because when active‚ the malM gene is not induced‚ so maltase is not utilized and the gfp gene is not expressed when maltose isn’t present (similar to our lab experiment when GFP is not expressed when arabinose is not present). other plasmids previously available were not capable of transforming Gram-positive bacteria that
