TRANSCRIPTION: Transcription is the process of which DNA matches corresponding RNA bases‚ Transcription is located in the Nucleus‚ and the only type of RNA that is involved in Transcription is mRNA‚ and the purpose is so that the code can get out of the Nucleus‚ mRNA is also made through Transcription‚ It also takes information that doesn’t directly make proteins but it helps makes codes for the production of proteins‚ DNA Transcription consist of 4 nucleotide bases‚ Adenine‚ Thymine‚ Cytosine‚ Guanine

Aspirin Synthesis Introduction Out of all the pharmaceutical drugs in the worlds‚ aspirin is made the most. Any potential pharmacist must be familiar with synthesizing the drug. The goal of this lab is to synthesize as much pure aspirin as possible. The reactants‚ acetyl anhydride and salicylic acid‚ must react in phosphoric acid. With phosphoric acid as a catalyst‚ the reaction yields aspirin and acetic acid. The equation for the reaction is as follows: “(CH3CO)2O + HOC6H4COOH □(→┴yields ) CH3CO2C6H4CO2H

During my junior year‚ I was required to write a synthesis essay about a topic of my choosing. As a woman considering a career in science‚ I researched the gender bias in the science field‚ and why it’s so apparent today. I didn’t realize that I would uncover article after article of individuals undermining the female gender. Ivy League Presidents‚ men with doctorates in Biology‚ and individuals with no background in science alike spread false and harmful information about women. After

Synthesis of Benzoin Date of Experiment: 1-26-15 Chelsea Price Lab Partner: Joey Simmons Abstract: In this experiment‚ benzoin was synthesized from benzaldehyde‚ using thiamine hydrochloric acid as a catalyst. The thiamine HCl was deprotonated by sodium hydroxide and acted as a nucleophile to attack the benzaldehyde. A water-cooled condenser was used to heat the solution at reflux. Vacuum filtration was used to wash and dry the product. The benzoin product was recrystallized

Effects of Differentiation on Enzymatic Activity Introduction HL-60 cells are capable of undergoing differentiation to induce different cell types. HL-60 cells can undergo morphological changes‚ changes in gene expression‚ and changes in protein synthesis. In the past weeks‚ we were able to conclude that HL-60 cells treated with DMSO and HL-60 cells treated with PMA will differentiate into granulocytes and monocytes upon treatment (1). We were also able to observe that both types of treated cells

The Co(acac)3 complex is used as a reagent instead of acacH because acacH cannot be directly converted to 3-nitroacetylacetone. Since Co(acac)3 is not stable in HNO3‚ Cu(NO3)2 and acetic anhydride are used in this reaction to produce the final product

synthesised is only 67%-70% and a maximum 70% yield of ester usually is not considered to be acceptable for a synthesis reaction‚ instead it is considering as a poor yield of ester. The synthesised ester can only have a maximum yield of 70% because for ester in which the carboxylic acid and alcohol are sterically unhindered‚ a same ratio mixture of carboxylic acid and alcohol can only synthesis ester with a maximum yield of 70% ester as the reaction with the same ration of mixture will reach a state

Objective: The benefit of this lab was to acquaint oneself with the fundamentals of the Aldol Condensation reaction by demonstrating the synthesis of dibenzalacetone (trans‚ trans-1‚5-Diphenyl-1‚4-pentadien-3-one) through the aldol condensation of acetone with benzaldehyde. The synthesis began by using a strong base to generate the acetone enolate ion. The ketone/enol tautomerization is an equilibrium process that produces little of the enol (ppm or less). However‚ any enol that formed quickly reacted
