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

Oedipus Complex in Hamlet In Shakespeare’s Hamlet‚ Hamlet’s personality can be explained by the Oedipus Complex. Throughout the play there are many times where he proves that he has Oedipus Complex. Oedipus Complex was not around at the time that that Hamlet was written. It just shows that Shakespeare saw the same personality complex’ as Freud. Freud first named the Oedipus Complex Theory in his book ‚ An Interpretation of Dreams‚ in 1899. Freud states "The child takes both of its parents‚

Task 1: Examine the Motherboard Procedure 1. Examine the following motherboard. One interesting thing you will see is the use of two BIOS chips. The M-BIOS chip is the Main BIOS chip and the B-BIOS chip is the Backup BIOS chip‚ which is used to rewrite the M-BIOS chip if it becomes corrupted. (Refer to the high-resolution imges for closer inspection.) 2. Using the Internet‚ locate information on the LGA 1156 connector. What processors is it used with? What is its purpose on the motherboard? A:

Synthesis of Aspirin Name: Xuanyi Li Teaching assistant: Deirdre Zwilling November 15‚ 2009 Purpose: To synthesize aspirin‚ a common analgesic drug‚ via nucleophilic acid-catalyzed substitution reaction of salicyclic acid with acetic anhydride. The whole reaction is catalyzed by phosphoric acid. (The experiment involved three parts: The synthesis of aspirin‚ the isolation and purification of aspirin‚ and the estimation of the purity of the final product.) [pic] Procedure[1]: A mixture

the development of complex societies‚ many different factors had a powerful impact on the way the societies developed. In some areas of the world‚ religion was the primary force that led to the creation of organized societies. Other areas developed on trade routes that made it necessary to develop complex societies to incorporate the growth of different economic classes and the wealth they generated into the structure of the government. In each part of the world where complex societies emerged

Abstract A complex number is a number that can be written in the form of a+bi where a and b are real numbers and i is the value of the square root of negative one. In the form a + bi‚ a is considered the real part and the bi is considered the imaginary part. The goal of this project is show how the use of complex numbers originates in the history of mathematics. Introduction Complex numbers are very important component of mathematics. They enable us to solve any polynomial equation of degree

In Life in the Iron Mills the narrator’s purpose is to inform the readers of the cruel realities of the lower class in hopes of change in the social structure. Davis captivates the attention of the reader’s by vividly describing Industrial America from the nightmare fog that covers the town to the hellish life of an industrial worker. Additionally‚ she creates sympathy by sharing the story of Hugh Wolfe; an iron mill worker with the desire for more‚ but with no opportunities is left with no hope

Jeana Greaves Chem3301-112 June 19‚ 2013 Synthesis of Aspirin from Methyl Salicylate Introduction The synthesis of Aspirin (Acetyl Salicyclic Acid) began with methyl salicylate and sodium hydroxide as the reagent. The polar oxygen accepts the electrons from now positively charged hydrogen. The positively charged sodium disassociates leaving the hydroxide ion with a negative Scheme 1 shows the mechanisms that were demonstrated during the synthesis of Aspirin. charge that attracts to the positively

Mixture that are uniform in composition‚ properties‚ and appearance throughout are called homogeneous. Sugar water is a homogeneous mixture and rocks is a heterogeneous mixture. Homogeneous and heterogeneous mixtures can be separated into their components by several physical methods. The methods that will use for the separation depend on differences in physical properties such as decantation‚ filtration‚ extraction and sublimation. The process of separating a liquid from a solid (sediment) by gently
