Double Helix Essay

Today, the 1953 discovery of the double helix, “the twisted-ladder structure” of DNA, by James Watson and Francis Crick, constitutes one of the greatest breakthroughs in the history of science. The discovery has given rise to the molecular biology of today and generated new insights into genetic coding upon which today’s multi-billion dollar biotechnology industry is founded. It laid the groundwork for other scientific achievements, including modern forensics and the mapping of the human…

The double helix: A personal account of the discovery of the structure of DNA is an account written by James D. Watson (1968), which describes the race to find the mystery of the DNA from the years 1950 to 1953. Watson manages to merge both the science with a fantastic tale to give a first-hand account about the journeys of the five main winners, namely, Francis Crick, Maurice Wilkins, Rosalind Franklin, Linus Pauling and himself. The race first begins when Watson, an American, finds himself…

In elementary school, my science club built a 5-foot-long DNA double helix model. My excitement for genetics and collaboration never ceased. At Columbia, I hope to "build" a strong academic base in biology. Whether I go into pharmacy or pharmacology, biology will be an integral part of my studies. Observing a man who was shot five times and another who had severe brain trauma from a motorcycle accident affected me. I encountered these patients while on rounds at the LSU Intensive Care Unit. I…

Results and discussions The results of optimisation for the first scenario reveals that the mechanical ventilated double skin façade operates at its optimum situation when the air cavity has its minimum possible dimension 0.05m with the ventilation rate equal 40 l/s. The successive optimisation process is provided in Figure 3. In the same way the outcome of optimisation…

Shunterrance Walton Mrs. Harper Comp. 1 23 Sept. 2016 A Double Life The double sports life is probably one of the best things to happen in high school. What is better than playing two of the most exciting sports in the school? Well, having those two sports at two different off seasons would be the best. More than likely, with me having an offseason is unimaginable. Playing two sports is not as miserable unless they carry on over to the next one. Do not get me wrong, I love basketball and…

with complete strangers. Some people like to do it hardcore. Some people like to watch others doing it. Over 20 million people are doing it. Safe to say, everyone’s doing it » and because of that double meaning, the ad was censored. Viewers won’t know the topic of the ad until the end. Despite the sexual double meaning,the old man is actually explaining how everyone is plays to call of duty. He is using the technique of Bandwagon : it suggests you that you should play and join the crowd and be…

true self. In literature, the use of a doppelganger or a double allows the reader to see the internal struggle of the character expressed externally – essentially uncovering a hidden nature. In the deathbed confession style tale of “William Wilson” by Edgar Allen Poe, a young man by the name of William Wilson travels the world attempting to escape his double. While sharing the same name, the two men are opposite in morality. William’s double acts as the protagonist in the story, constantly…

Victor Frankenstein and Robert Wringhim aim to transcend their social and spiritual positions through, respectively, scientific and religious pursuits. In doing so, however, they are confronted with ‘another version’ of themselves in the form of a double: the Creature to Frankenstein, and Gil-Martin to Wringhim. ‘Anxiety about the…

Novels, plays, and movies often depict characters caught in a conflict with their doubles. Such collisions call a character’s sense of identity into question. The film The Double by Richard Ayoade takes Fyodor Dostoyevsky’s original book The Double and plays it with a modern twist. Upon closer inspection of Fyodor Dostoyevsky’s The Double and its movie adaptation by Richard Ayoade, we see that though both share many elements and plot progressions, the movie, as a more modern medium, utilizes its…

1. Most aquaporins have a similar structural arrangement, consisting of a similar fold. This fold contains helices encasing a small water-conducting channel where water is able to arrange in a singular line. There are cytoplasmic and extracellular loops immersing into the membrane through opposing sides, and form two smaller helices creating a psedo transmembrane segment. Within the membrane, there are four aquaporin molecules forming a homo-tetramer, creating a fifth channel; the channel is…
