The story of the Bible’s Queen Esther is filled with intrigue‚ romance‚ bravery‚ and honor. It is the story of a Queen who became the savior of her people through a curious mix of

ineffective. In order to help resolve the crisis‚ antibiotics were found through screenings of soil microorganisms. However‚ soil microorganism’s antibiotics were depleted by the 1960s and their antibiotic effects were unable to be replicated through synthesis. In this experiment‚ the researchers developed numerous methods to cultivate uncultured organisms in their environment. The goal of this experiment was to find antimicrobials in the uncultured soil. Through this successful experiment‚ the researchers

follows a semi microscale technique even a small amount of lost product yields a great loss in the yield 4. These sources of error could be minimized by doing a larger reflux in order to increase the yield. However‚ as the purpose was to simply synthesis SnI4 in order to identify the stable oxidation states (the melting point range requires very little product) it would be advantageous to use the current method. This is due to the smaller quantity of materials needed for this type of reflux‚ thus

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

In this lab we employed various assays utilizing a biuret reagent‚ coomassie brilliant blue reagent‚ and ultraviolet light in order to determine the identity of six unknown solutions and the concentration of a bovine serum albumin sample. We were given three samples that lacked protein‚ and three samples containing proteins‚ and using a spectrophotometer we assessed the amount of light absorbed versus the light transmitted‚ based on the principles of the Beer-Lambert Law. The three proteins used

A small amount of the unknown (approximately the tip of the spatula was used for all the pigments) was added into each clean dry test tube. For the first test 1 mL of 3 M of HNO3 was added. As soon as the acid came into with the solid‚ the pigment was observed to dissolve while also turning the solution into a pale clear colour. The same amount was used for the HCl reagent. As soon as the acid touched the pigment it yielded in a clear solution (solid dissolved after a few shakes). When the KI was

As shown in the balanced chemical reaction in figure 1‚ Felbinac is synthesized from 4-bromophenyl acetic acid‚ phenylboronic acid‚ and 10% Pd/C. Figure 1: The balanced chemical reaction showing the synthesis of felbinac. It functions by inhibiting cyclooxygenase-1‚ which releases prostaglandins that cause pain as a response to injury. In a study conducted by Moore et al.‚ 160 patients were subject to various topical NSAIDS to determine their effectiveness

Every cell‚ whether it belongs to a plant‚ bacteria or a human‚ requires energy from varying food sources to survive. However‚ when cells break down food into its sugar components‚ i.e glucose‚ they cannot use the components directly because glucose holds a lot of energy it would be inefficient to use for reactions that don’t need a lot of energy. Imagine you want to buy pencils for $5 from a store that won’t give change‚ it is more economical to use a $5 or $10 bill than a $100‚ that way there is

If I want to target the peptide to different compartments‚ I would use specific signal sequences or uptake-targeting sequences encoded into my peptide. Signal sequences contain information that will target the peptide to a particular organelle. The information is usually encoded within amino acid sequences of the protein itself‚ usually within the 20-50 amino acids. Also‚ each organelle has specific set of receptors that bind only to the specific signal sequences‚ thus making sure of target specificity

1. In the Luminol synthesis the compound being oxidized was the sodium hydrosulfite. 2. The purpose of the acetic acid is to pronate the dianon organic molecule to make the neutral organic compound‚ Luminol that will crash out of the solvent. If the number of moles were reversed for acetic acid and sodium hydroxide the solution would be very basic‚ and and the amount of Luminol produced would decrease. 3. The cold water was used to decrease the solubility of Luminol in the solvent and prevent further
