The Spot-Overlay Ames Test was used in the lab to find the mutagenesis of Diet Coke and ThermaFlu. Along with these substances three mutant strains of salmonella were also tested. TA 1535‚ TA 1537‚ TA 1538 all lacked the ability to grow the amino acid histidine unless reverted back by the potential mutagens. After the first week of testing‚ results showed that both of the potential mutagens‚ Diet Coke and ThermaFlu were in fact mutagenic. This was established if colonial growth was at least twice

Conditions That Can Affect Blood Results Using Luminol The purpose of this science experiment was to discover under what conditions can blood give a false result using the presumptive test called luminol. In order to better grasp the experiment‚ research was conducted on several subtopics: the basic concept of luminol‚ the basic concept of artificial blood which is being used for this experiment instead of legitimate blood‚ and substances interferences that could tamper with crime scene results

Analysis of Alcohols‚ Aldehydes and Ketones Karl Wayne Mancao‚ Raphaell Mordeno‚ Andres Pastrana III*‚ and Shannen Peñaverde Department of Biology‚ University of Santo Tomas‚ Manila‚ Philippines Abstract The proponents have done several tests for identifying alcohols‚ aldehydes and ketones. These tests are Dichromate test‚ Tollens test‚ Lucas test‚ DNPH test and Iodoform test. Three samples got positive result in dichromate test and one in Tollens test. Lucas test got one sample that has

saturated fatty acid is an example of carbon atoms that have a single bond between them; however‚ an unsaturated fat has double bonds. Amino acids are known as the building blocks of proteins‚ they contain at least one carboxyl group and at least one Amine group. They perform many important functions such as: building cells‚ protecting the body from viruses or bacteria‚ repairing damaged tissue and carrying oxygen throughout the body. Replenishing amino acids immediately following exercise is critical

nitrogen‚ but unlike nitrogen‚ has the ability to expand its valencey from 3 to 4‚ 5‚ or even 6 (1). The stable 5 valencies are met in compounds like phosphoric acid and PCL (1). Wittig discovered that phosphines‚ which are the phosphorus equivalent of amines‚ easily form phosphonium salts with alkyl halides and that these salts readily lose HX with strong base. This product is called an ylide or a phosphorane. The ylide is a polar molecule with a carbanionic carbon. Figure 1. How to make a phosphorus

Introduction The Central Dogma of Molecular Biology Cell DNA Transcription mRNA Translation Ribosome Polypeptide (protein) Protein Synthesis Flow of Information: DNA RNA Proteins Transcription Translation Transcription is the process by which a molecule of DNA is copied into a complementary strand of RNA. This is called messenger RNA (mRNA) because it acts as a messenger between DNA and the ribosomes where protein synthesis is carried out. Protein Synthesis
