Watson And Crick Essays - Sigma Xi, Nucleic Acids,

Watson And Crick James Watson and Francis Crick James Watson is a biochemist and Nobel laureate. He attended school at the University of Indiana, after graduating from the university he joined of the faculty at Harvard University. Before joining the faculty at Harvard he did postgraduate work with Francis Crick in the Cavendish lab, at the University of Cambridge. Watson and Crick worked out the deoxyribonucleic acid molecule. This is a substance that transmits the genetic characteristics from one generation to the next. They both thought that it should be possible to correctly guess its structure, given the experimental evidence of Kings College. They also thought they could figure out the possible stereochemical configurations of polynucleotide chains. They did there first serious effort, in the late fall of 1951 and it turned out to be unsatisfactory. On their second effort they had more experimental evidence, and put more appreciation into the nucleic acid literature. Watson not only worked on the DNA structure he also did some work with Alexander Rich on the RNA. Another one of Watsons experiments was the structure of TMV, using X-ray diffraction techniques. This was to see if chemical sub-units, were helically arranged. This was achieved in 1952, when use of the Cavendishs newly constructed rotating anode X-ray tubes allowed an unambiguous demonstration of the helical construction of the virus. Watson and Crick have helped the world in more ways than one. By experimenting with DNA they have helped us to figure out human genetic questions. Their experiments also can lead into other things, such as maybe cloning the human DNA strand. Science Essays

The best idea of regulating guns in the United States is restricting the purchase of bullets

The best idea of regulating guns in the United States is restricting the purchase of bullets Reason # 1: Tracking the buyers of bullets makes it easier to regulate guns in the United StatesAdvertising We will write a custom essay sample on The best idea of regulating guns in the United States is restricting the purchase of bullets specifically for you for only $16.05 $11/page Learn More Guns are nothing but empty vessels without ammunition and so it would help a great deal if the authorities regulate the acquisition of bullets. Anyone who should not own a gun should also not own a bullet, but because guns last longer, outlawed criminals can possess them without suspicion. On the other hand, the lifespan of a bullet is just one shot which makes it easier to link the shooter and the purchaser. Currently, New York has a limit of seven rounds of ammunition per magazine. In addition to this, ammo dealers who register with the state, have purchasers’ records and this enables the police to get alerts in case an individual is stocking on bullets (Hen derson and Trotta 1). Tracing the link between the shooter and the buyer requires the cooperation of the dealer. This is the path trodden by Sacramento officials who require ammunition sellers to take the fingerprints and names of their customers. They transfer this information to the police who double check it with the criminal database of the FBI. Greg Halstead, a police detective in Sacramento, says that this practice is helping them to retrieve illegal guns from homes that he would not normally bother searching through. We can also deduce that it prevents shooting crimes from occurring because the police are able to point out illegal buyers and trace them from the fingerprints. Captain Bill Hart of the Los Angeles Police Department seconds Greg Halstead’s argument. He says that Los Angeles has become a safer place because of the records sent by ammunition dealers, which they look through to chaff out the illegal owners. Other states therefore need to follow suit and requi re sellers to log their sales so that illegal buyers find no place to shop for bullets (Henderson and Trotta 1). Reason # 2: Engraving serial numbers on ammunition boxes can help regulate gunsAdvertising Looking for essay on government? Let's see if we can help you! Get your first paper with 15% OFF Learn More A study by Glenn Pierce of Northeastern University states that a significant number of ammunition purchases are by illegal possessors. He goes on to add that engraving serial numbers on ammunition boxes would be a significant step towards the realization of gun control in the United States. This is because serial numbers allow the police to easily trace the link between a bullet and a buyer. Moreover, he considers it as a move that would sharply reduce the bullet supply of the illegal market (Pierce 309). A 2005 California bill seeking to put this idea into law was shot down because the ammunition industry argues that it would lead them into bankruptcy. Other than that, they also think that the serial numbers are not always legible. These arguments do not hold water because people’s lives are still at risk and there is a need for the Ammunition Coding System and the ammunition industry to come to an agreement that favors both sides and protects the general population (Koper, Woods and Roth 18). Reason # 3: Restricting the purchase of bullets reinforces the ban on bulk buying to effectively regulate guns in the United States Some authorities in the United States are already making steps towards regulating guns by prohibiting the purchase of bullets in bulk. This is a good idea but not as effective as it should be. New Jersey, for example, places a ban on bulk buying of ammunition in the hopes that it can help curb the menace of gun violence and generally regulate guns in the United States. However, a 2004 study in Jersey City concludes that the ban on large capacity magazines has a very small impact in regulating guns becaus e criminal shootings tend to use less than five rounds. Therefore, this ban only serves to irk the members of the National Shooting Sports Foundation who argue that they need more that 1,000 rounds of ammunition during a typical weekend trip of range shooting (Murphy 1). We need to realize that placing restrictions on bulk buying only does not prevent criminals from laying their hands on bullets.Advertising We will write a custom essay sample on The best idea of regulating guns in the United States is restricting the purchase of bullets specifically for you for only $16.05 $11/page Learn More As a matter of fact, the state should concentrate on restricting all forms of ammunition ownership if they want to zero in on the criminals and achieve gun control in the United States. By restricting the purchase of bullets, the authorities reinforce the ban on bulk buying and manage to get effective results in achieving gun control (Pierce 310). Reason # 4: Banning s ales of ammunition via mail-order can help regulate guns in the United States In 1968, The Gun Control Act placed a ban on the sale of bullets through mail-order and even had dealers log their sales. This was however shot down in 1986 by the implementation of The Firearm Owners’ Protection Act which generally led to the loosening of gun control (Spitzer 27). Eliminating controls on transfers of ammunition is definitely a bad move because today we have high capacity magazines that are easily accessible over the internet. This platform allows the buyer to remain anonymous even to the seller because he does not conduct a background check of any sort (Reedy 1). Once a criminal shooting occurs, it would be hard for the police to link the bullet to the buyer because the seller is not able to provide any substantive information about his client. It is therefore necessary to reinstate the ban on the sales of bullets via mail order to put an end to the ghost clientele and regulate gun s in the United States (Lioncourt 1).

Stock Portfolio Analysis - Coke and Pepsi Term Paper

Stock Portfolio Analysis - Coke and Pepsi - Term Paper Example The annual expected return for Coke is 0.1307, while the annual expected for Pepsi Company is 0.0482. This means that Coke offers an expected higher return for an investor that Pepsi Company. However, the investment that an individual is willing to make is also measured by the risk attached to the investment. The risk that is attached to an investment means the potential variation of actual returns from expected returns, a factor that is measured by the variance and standard deviation of an asset or portfolio. From an analysis of Coke and Pepsi Companies, it is evident that Pepsi has a higher standard deviation and variance, albeit by a small percentage. The standard deviation and variance for Pepsi are 0.048 and 0.0024 respectively, while the standard deviation and variance for Coke are 0.046 and 0.0027 respectively. This means that Pepsi’s stock has a higher deviation from expected return, so an investor who is risk averse would prefer to invest in Coke. The other factor tha t is used to determine the expected return of a stock is the beta, which refers to the relative volatility of the stock to the market. From the analysis, it is evident that Coke has a higher beta of 0.54 compared to Pepsi’s beta of 0.52, which indicates that Coke’s Stock is more volatile in the market. The covariance of two stocks in a market indicates that extent to which the returns for the two investments move in relation to each other. The covariance for Coke and Pepsi is low at 0.002, which means that the stocks co-vary. An investor with an aim of diversifying stock should not invest in the two stocks together. The correlation of stocks refers to the extent to which the prices of the two stocks affect each other, and from the analysis, a correlation of 0.7 indicates that the prices of the two stocks are strongly correlated, since the two stocks are strong competitors. Coke and the Market The annual return for Coke is higher than the annual return displayed by the market, which indicates that Coke is performing better than the market. The annual return for coke stands at 0.1307, while the annual return for the market is -0.009. However, the market has a lower risk than Coke, as can be seen from the standard deviations of the two portfolios. The variance and standard deviations for the two are 0.0027 and 0.0467 respectively for Coke and 0.0030 and 0.0214 respectively for the market. This indicates that Coke has a higher chance of risk than the market, which would be the ideal choice for a risk indifferent investor. The covariance of

Rap music's effect on American culture Research Paper

Rap music's effect on American culture - Research Paper Example Corporate brands such as Nike, Coca cola, Sprite, McDonalds, in addition to many more corporate giants have been able to capitalize on this phenomenon. Despite the fact that hip hop and rap culture critics seem to be fixated on messages like violence, harsh language, and sex, the genre has a plethora of positive tenets ascribed to it. This art form has substantial potential of mending ethnic relations (Dill 2009). Between 1950 and 1960, the ‘beat culture’ acted in challenge of the status quo in a manner that has greatly unified individuals (the youth in particular), across a diverse ethnic spectrum. Recent years have seen mounting controversy surround rap music, and at the heart of the American media. From the West Coast-East Coast hype that marked the murders of rappers Notorious B.I.G and Tupac Shakur, to the castigation of modern music in light of Littleton Colorado’s school shootings, it appears that media and political groups have quickly blamed rap for an ap parent trend of youth violence. Rap music, in a similar fashion to other music forms, cannot be comprehended until it is studied minus the frame of its social and historical context. Today, rap music ascribed its origin to the hip hop culture of urban, working-class, young African-Americans, and its roots in the oral traditions of Africans. Its function is seen as the voice of an otherwise underrepresented group, and its popularity has grown along with appropriation and commercialization by the music industry. The paper herein discusses the rap music as a genre and its influence on America (Dill 2009). Rap’s commercial history can be traced back to 1979, the year during which ‘the Sugar Hill Gang’ released the considerably successful song known as ‘Rappers Delight’. Contemporary rap music’s beginning can be traced back to the mid-1970s in the Bronx. Rap music was a way for the urban black youth to express themselves rhythmically. Rap music together with

The Truth is Out There do we Wish to Know :: Free Essay Writer

The Truth is Out There do we Wish to Know The Heart of Darkness The search for truth and knowledge consumes us all at some point in our lives, but we don’t always find what we are looking for in Truth. We wish it to be definitive, but more than that, we search for it with the strong belief that we will find it and be pleased, pleasantly enlightened, and will live better lives for it. In Heart of Darkness, it is shown that this is seldom true. Kurtz was destroyed by the truth he discovered about himself and the world he lived in. He had known and believed a "white" truth about the world he knew. His white truth was one of civilized, genteel ideas and actions. Living amongst the privileged few, the artists, musicians, orators, and other cultured people, he knew nothing of the dark depths of the human heart. When confronted with those horrible realities, he was forced to learn the "black" truth about life and people. His mind couldn’t comprehend the truths he had to accept; it was totally contradicting to what he knew, and so he crumbled, selling his soul to sit among demons and devils. He was hollow inside, had no sense of moral or social responsibility, and the black truth he discovered ate away and destroyed him. He regressed to savage behaviors he had previously repressed and let the darkness fill the cold void within him. Because he knew so much blackness, he was unable to live in society again. He cros sed over and relinquished all ties to the civilized world, for he had lived the white truths to an extreme, so did he live the black truths. Kurtz showed what happens when the white truths and lies of society are taken away. Kurtz lived and found sustenance in that reality, when it vanished and was replaced by another, darker world, he folded. In our society, we live by restraint. For Kurtz in Africa, all the restraints were removed and he was allowed to have as much candy as he wished, even before dinner. This proved to be too much for him, he went to an extreme and was destroyed by the excesses he craved, the very excesses that drove him to the top of the tribes and peoples he conquered.
