Stanley Miller Paper - Coursework Example This is because a concentrated solution would respond better than a dilute solution with diffuse molecules. IX. Paper chromatography is a method of separation and identification of compounds. It utilizes the principle of capillarity and also solubility (to facilitate separation). Colour is often used to allow the identification of compounds. The properties include; molecular weight, structure, shape of the molecule, and the polarity of the molecule. XII. He was able to tell the presence of the amino acids by the ninhydrin indicator. For their individual discrimination, he used comparison of spot size and colour to known templates of characterized amino acids. XIII. Miller knew the total yield was in the milligram range by informed inference. Knowing that the system was closed, the total mass of reagents remained the same (gases included). By weighing the remaining fractions in the flask, and subtracting impurities by silica, he may have obtained a rough idea of the amount. That is; total mass of reagents (minus apparatus) = Amino acids mass + remaining reagents(minus impurities). It though may not be entirely accurate, as the amino acids existed in aqueous state, thus requiring the factoring in of water of dissolution. XV. His experiments did test his hypothesis. Though not accurate in the reproduction of the original setting of primitive earth, they showed that indeed it was possible that the primitive atmosphere contained the right inorganic molecules, the right conditions and the right amount of energy to produce organic molecules. XVI. A good experiment to do next would be one on synthesis of nucleotides. If amino acids could be produced, then similarly, nucleotides might also have been produced, sparking the beginning of biological
