Sarah Khan Bivins-5th April 20th‚ 2013 Protein Synthesis Every day‚ you take in an abundance of different biomolecules; one of them being proteins. Have you ever wondered how proteins are made? They don’t just grow from a tree or fall from the sky‚ they are made through a process called protein synthesis. Protein synthesis is broken up in two two steps: transcription and translation. Transcription starts inside the nucleus when the DNA is unzipped by helicase. Following that‚ the mRNA nucleotides

been something that has come easy to me‚ especially when put on the spot and told to write a paper in a certain amount of hours. When I write‚ I like to have time to think and plan my essay. Being able to revise and edit the paper makes it even better than it was before. When I am given the time to plan my essay‚ the writing has more depth than when I am put on the spot and have no time to think about what will go into my paper.

CHEM3412 Synthesis of a Porphyrin Porphyrins are hetereonuclear‚ macrocyclic compounds that play an important role in living organisms. Examples include the non-protein heme portion of hemoglobin in animals whereby the lone pairs on nitrogen can bind to the oxygen-carrying iron. In plants‚ chlorophyll uses the vast conjugation to allow absorption of light for photosynthesis. The characteristic colors of porphyrins is also due to the conjugation. An examination of the porphyrin structure

Identifying sites of protein synthesis in Chlamydomonas using erythromycin and cyclohexamide as protein synthesis inhibitors. October 16‚ 2009 Introduction: In living cells‚ prokaryotic or eukaryotic‚ the synthesis (construction) of proteins is accomplished by similar machinery. Amino acids‚ ribosomes‚ messenger RNA (mRNA)‚ and transfer RNA (tRNA)‚ are all necessary for the building of functional proteins in a cell. Ribosomes are the site of protein synthesis in a cell‚ and there are two

Lab 1: Synthesis of Aspirin Introduction: The purpose of this lab was to demonstrate the ability to easily alter the molecular structure of a compound to greatly increase its utility. In this case‚ an acetyl group was added to salicylic acid‚ a naturally occurring compound with significant pharmaceutical value. Without the addition of the acetyl group‚ salicylic acid is an irritant to the gastro-intestinal (GI) tract. Once the acetyl group is added via a simple reaction‚ acetylsalicylic

Pretending Not To Care Friedrich Nietzsche once said‚ “What does nihilism mean? That the highest values devaluate themselves. The aim is lacking; ‘why?’ finds no answer”. Nietzsche reasons that when a society values anything—an object‚ a person‚ or a philosophy—it becomes a challenge to see who can obtain it‚ and those who cannot‚ form this idea that the value is pointless. He goes on to say that while those who cannot obtain it may act like they don’t care about this value‚ they still ask ‘why

The question we need to be asking ourselves is if we should be letting our 13 and 14 year old teens read the book‚ “The Adventure of Huckleberry Finn.” With this type of society‚ I personally think we should not. The reason I think that is because I feel like 13 and 14 year old teens are not yet mature enough to understand Mr.Twain’s intentions. “The Adventure of Huckleberry Finn‚” was an anti-slavery and anti-racist book‚ but I feel like there is a correct time to read a book like this one.
