REPORT 1. 2. The unknown code is an amino acid‚ Glycine. To justify the reason is because the retention factor is the same exact number as the Glycine. The data of the unknown shows everything to be exact with the data of the Glycine 3. The mobile phase is the more polar during the capillary action of the experiment. As soon as the paper touches the mobile phase‚ the solvent rises to the amino acids. This is where you can find polarity of the amino acids. 4. Based on the nature of the mobile

And with DNA: GAC - AGC - CGA - same 3 ’letters’; completely different meanings to the cell (specifies the amino acids Aspartic Acid‚ Serine‚ and Arginine) Q: Review: What are genes? A: The DNA in each chromosome that DOES provide the instructions for a protein is called a gene. * In the 1940s‚ scientists proposed‚ fairly correctly‚ that each gene "codes for" (contains

Title:Identification of Amino Acids and Proteins Introduction : Amino acids are molecules containing an amine group(NH3)‚ a carboxylic acid group(R-C=O-OH) and a side-chain( usually denoted as R) that varies between different amino acids. The key elements of an amino acid are carbon‚ hydrogen‚ oxygen‚ and nitrogen. Proteins are biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form in a biologically functional way. A polypeptide is a single

ACIDS AND BASES The reason that acid-base reactions are so important is that many of the things you come into contact with on a daily basis are either acids or bases. Most fruits are acids‚ as are carbonated beverages‚ tea‚ and battery acid. Common household bases include baking soda‚ ammonia‚ soap‚ and antacids. What are acids and bases? There are not one but three common definitions used to describe acids and bases: 1. Arrhenius acids and bases 2. Brønsted-Lowry acids and bases 3. Lewis acids

Vol. 1 ACETIC ACID 115 ACETIC ACID 1. Introduction Acetic acid [64-19-7]‚ CH3COOH‚ is a corrosive organic acid having a sharp odor‚ burning taste‚ and pernicious blistering properties. It is found in ocean water‚ oilfield brines‚ rain‚ and at trace concentrations in many plant and animal liquids. It is central to all biological energy pathways. Fermentation of fruit and vegetable juices yields 2–12% acetic acid solutions‚ usually called vinegar (qv). Any sugar-containing sap or juice can

Conclusion 3.2.1 1 Describe how the DNA code is translated into messenger RNA. DNA is translated into messenger RNA through transcription and translation. DNA is split through transcription and then it is translated to match into RNA. 2 How is the RNA molecule a “script” for the protein production process? RNA is a script for the protein production process because they set the RNA up to translate into a protein. 3 What is the function of hemoglobin in the body? Hemoglobin functions in the body by
