Double Helix Essay

The fight to discover the structure of deoxyribonucleic acid continues in James Watson’s The Double Helix. Linus Pauling thought he had discovered the structure of the acid, but in fact he had come with an incorrect structure that did not represent an acid at all. The basis of Pauling’s model consisted of a three-chain helix in which the sugar-phosphate backbone resided in the center of the molecule. The phosphate groups in this theoretical structure were not ionized. Instead, each phosphate group had a hydrogen atom bound to it, which added a positive charge to each group, leading to each phosphate group to have a net charge of zero. However, the definition of an acid goes against this as an acid should have a positive charge, as Watson very…

The book I read for my Biology book report was, The Double Helix, A Personal Account of the Discovery of the Structure of DNA an autobiography written by James D. Watson. It was released in 1968 and was published by Atheneum Press (US), Weidenfeld & Nicolson (UK) and is 226 pages. As the title suggests, the book is Dr. Watson’s personal account of the groundbreaking discovery of the structure of DNA. Biologists already knew that genes were the material responsible for traits getting passed from…

“The Double Helix” by James Watson of Watson-Crick fame is a scientific memoir with a difference. Watson describes the period before and after the famous Letter to Nature paper about a possible structure of DNA, not scrimping on the details and being quite frank. The picture that emerges from the book paints Watson as a generator of (mostly incorrect) ideas with an aversion to experimental science and an interest in au pair girls – not what I expected from one of the most famous biologists of…

1. Francis Crick Crick discovered the relative distances of the repetitive elements in the DNA molecule, and the dimensions of the monoclinic unit cell which indicated that the molecule was in two matching parts, running in opposite directions. He also, in collaboration with Watson discovered the material that our genes are made of and put forward the model of the double helix DNA structure which included the measurements of the angels formed by different chemical bonds. Crick in collaboration…

Shedding light upon what it means to be a scientist and the true scientific process, Watson 's “The Double Helix”, Lynne Osman Elkin’s “Rosalind Franklin and the Double Helix”, and NOVA 's Photo 51, bring together different perspectives of the epic adventure to reveal the truth of the “secret of life” and the often unseen inner workings of the world of science (Watson 197). The journey to the structure of DNA took many trials and errors, yet the most significant moments might be those…

The Truth Unveiled What if a boy grew up having a great relationship with his parents and then lost them both, well this is the life of Eli Samuels. Eli’s mom went crazy because of Huntington’s disease and he and his dad drifted after she moved into the nursing home. Now Eli is at risk of getting Huntington’s disease and becoming insane. So in order for him to protect the people he loved, he left them. Throughout Nancy Werlin’s Double Helix Eli Samuels and his father never got along because of…

The Double Helix is the shape of DNA. It’s a lot like a twisted ladder; with A’s, T’s, C’s, and G’s as the rungs. The way that they all fit together makes it the shape of a double helix. That’s interesting and all, but the question is who is the real discover? The Double Helix was discovered by Rosalind Franklin, but she didn't understand its importance and true meaning, so all the credit goes to James Watson and Francis Crick. The Double Helix was founded by Rosalind Franklin. In the article…

DNA: The Double Helix Introduction: DNA stands for DeoxyriboNucleic Acid. It is a type of Nucleic Acid, which has deoxyribose sugar in it instead of ribose. DNA has a double helical structure. By double helix, the meaning is two strands of polynucleotide running parallel and coiled around each other through hydrogen bonding. DNA is hereditary material in all the living organisms on this planet. The basic mystery behind its heredity nature resides in the same double helical structure. The double…

In the novel Double Helix a man named Eli takes the reader on a journey where he learns who and what he is. On this quest to find out who he actually is, he faces some family obstacles and overcomes them in order to seek the truth. Eli himself is an 18 year old man who just graduated high school and plans on taking a year off of school to work at Wyatt Transgenics. Eli isn’t an ordinary person. He is extremely smart, unusually tall and extremely athletic. He has always known these things, but…

The story of Rosalind Franklin not only emphasizes the important role od women in the field of science, it also discusses the challenges and obstacles that woman of science faced and continue to face. Although Watson and Crick worked to study the structure of DNA, they would not have been able to complete their research without the Photo 51; a photo stolen from Rosalind Franklin. Although Franklin was so integral to the discovery of the structure of DNA and her work was stolen from her, she was…
