Recombinant DNA Report Our final annotated gel image sums up the successful experiments we performed over the course of 8 weeks. The image will be referred to throughout the report: Lane 1: 10 µL of ladder. Lane 2: 20 µL of a pAMP- EcoRI/HindIII double digestion. Within the double digestion‚ one can find 8 µL of pAMP‚ 1 µL of the EcoRI enzyme‚ 1 µL of the HindIII enzyme‚ 5 µL of 10x Buffer 2.1‚ and 35 µL of water. A total volume of 50 µL was present

DENATURATION OF PROTEINS Abstract The experiment was done to be able to understand how various denaturants such as HCl and NaOH affects proteins. It was observed that different denaturants act upon or denature protein differently. This was determined using the principle of viscometry. An Ostwald viscometer was used to measure the viscosity of the prepared native‚ blank‚ denatured native and blank with denaturant solutions. The time required for the said solutions to pass through the viscometer

The Grignard Synthesis of Triphenylmethanol Organic Chemistry Lab II March 19‚ 2012 Abstract The purpose of this experiment was to synthesize the Grignard reagent‚ phenyl magnesium bromide‚ and then use the manufactured Grignard reagent to synthesize the alcohol‚ triphenylmethanol‚ by reacting with benzophenone and protonation by H3O+. The triphenylmethanol was purified by recrystallization. The melting point‚ Infrared Spectroscopy‚ 13C NMR‚ and 1H NMR were used to characterize and confirm

Objective: The objective of this lab is to determine and analyze the many chemical qualities of copper ‚ by using many solutions that enable copper to undergo chemical changes that will take copper from a metal back to its original state. This is done using cooper‚ Concentrated HNO3‚ 6 M NaOH ‚ Bunsen burner‚ 6 M H2SO4‚ Mg ribbon‚ and two test tubes. The techniques used in this lab which is cleaning glassware‚ disposing of chemicals ‚ measuring mass ‚ centrifugation ‚ venting gases‚ and test tube

The history of DNA structure discovery(sec.4.1): 1869- Johan miescher •studies the nuclei of white blood cells(isolated th material using HCL and digestive proteins •Named the substance nulclein and also found the material was rich in nitrogen and phosphorus. 1919-Pheobus levene •Discovered that DNA was made of chains of nucleotides *see nucleotide structure* 1920 DNAvsRNA * see chart •Thought that 4 nucleotides were connected in the same repeated pattern •protein gas 20 amino acids

(NH2CH2CH2NH2) that formed [Co(en)2(H2O)2]Cl. Then the [Co(en)2(H2O)2]Cl was reacted with H2O2 to change the cobalt’s charge to cobalt(III) from cobalt(II). Finally HCl was added into the solution to form [Co(en)2Cl2]Cl. The percent yield was 45.51%.To synthesis trans isomers of [Co(en)2Cl2]Cl‚ distilled water was first mixed with CoCl2▪6H2O‚ the solution color was changed to wine color. After ethlenediamine (NH2CH2CH2NH2) was added‚ the color of the solution changed to blood color‚ and kept its color until

In this experiment‚ we used simple distillation and extraction to do synthesis of 1-bromobutane. The experiment was carried out by mixing 13.3 g of sodium bromide‚ 15 mL of water and 10 mL of n-butyl alcohol in a 100 mL round bottom flask. We cooled the mixture and added 11.5 mL of concentrated sulfuric acid. Then the mixture was heated at reflux with a short condenser for 45 minutes and then we drained out the condenser. We removed the condenser and distillation head was set up to set up the condenser

This lab must be typed. Title DNA Fingerprinting Purpose Why are we doing this lab Background 1. What are restriction enzymes 2. When added to a DNA sample‚ what do restriction enzymes do 3. What do you call the specific sequence of bases the enzyme is searching for 4. What is a restriction digestion 5. What is the purpose of the water bath 6. The electrophoresis apparatus creates an electrical field with positive and negative poles at the ends of the gel. DNA molecules are negatively charged.
