What is the double helix? The double helix was a starling breakthrough. The double helix experiment and idea led to the discovery of the structure of DNA, all thanks to five very important people in history. A double helix is a double parallel spiral. This lively discovery was enormous and was the most influential and successful biological fining since Charles Darwin. The discovery and foundation of the double helix structure of DNA, a hereditary molecular structure, sparked science, scientific research, and the advancement of opportunities. Although this took a lot of effort and time, this breakthrough discovery has changed the subjects of science, chemistry, biology, anatomy, and physics completely around. Although this discovery has prompted science in our world today, little do we know a young man tried to stop this. The Double Helix by James D. Watson tells us the story of this great discovery throughout our history. Throughout this book there is so many key relevant topics that I can …show more content…
It took so much time, understanding, and knowledge. This book was very interesting and yet, factual. I learned a lot from it and really changed my thoughts and knowledge and biological and molecular science. One thing I found interesting was that it was not just a Crick and Watson that discovery this structure, it was more than these two key people. I love the depth throughout the novel which gives us the information that Maurice Wilkins, Rosalind Franklin, Linus Pauling, Francis Crick, and James Watson established this discovery. Many people throughout our nation do not know that it was more than Crick and Watson that led to this remarkable discovery through our history. Another aspect that is astonishing is that fact Crick and Watson were so close to giving up on the research of DNA and it's double helix structure. They believed it would impede science and it's research. It held
The discovery of deoxyribonucleic acid, more commonly known as DNA, has been the foundation for much scientific work. This fundamental discovery was credited to James Watson and Francis Crick. Many people believe that another person, Rosalind Franklin, also played a large role in the research. How much did she contribute to the discovery? Why is her name left unrecognized? This paper will discuss her part in the search and whether her name should appear next to Watson's and Crick's as the co-discoverer of DNA.
2. What role did James Watson & Francis Crick play in our understanding of DNA’s structure? They discovered the 3D structure.
When Pauling and Cory attempted to come up with the structure of DNA, they thought that the DNA helix was a triple helix. This was because they misinterpreted DNA A structure and concluded that the phosphate and sugars were on the inside and the nucleotide bases were on the outside. Watson and Crick said this was not possible because phosphates can’t fit together inside the helix without breaking their molecular bonds. The studies Watson and Crick made were based off of DNA B molecule from the X-ray of DNA B taken by Rosalind Franklin that had low concentration, rather than A DNA which was high in salt concentration that gave Pauling an improper representation of the DNA helix. Pauling and Cory stated that the helix was made of three helices, Watson and Crick disapproved of this concept because phosphate backbones are negatively charged, it was impossible to put three negatively charged strands with each
Over the course of the modern age, the human body was still a mystery waiting to be solved. The body contains secrets one can only hope to discover. Over the twentieth century, scientists tried to understand one of the most complex concepts in the biological field. DNA (Deoxyribonucleic acid) was at the forefront of research. Several theories claimed to have solved the structural concept of DNA. However, it was not until Francis Crick and James D. Watson discovered the true structure, the double helix. However, many potential models of DNA had passed through the biology field until eventual lose of credibility. The past models would contain a fixed detail that would make the entire concept invalid. In James D. Watson book, The Double Helix, he illustrates his path amid incorrect theories until he reaches the model that is taught around the world today.
Watson and Crick discovered that cell’s nucleuses contained a molecule that was called deoxyribonucleic acid, or DNA. The clues from the diary are: “Even us lab boys knew that there had been gossip going around the labs that Crick and Watson had been trying to solve the structure of this new-fangled molecule called DNA – deoxyribonucleic acid – but discovering the secret of life itself?”

James Watson is both the narrator and author of the novel “The Double Helix.” The reader begins to understand this character by the actions and ways this character is treated. He is at the time 19 years old and graduated from the University of Chicago. James Watson is a character the reader can relate to with events such as James not just focusing on science, but enjoying parties and meeting the girls at Cambridge University. He is portrayed as a very determined scientist as he throughout the novel. He shows this when he studies RNA, bacterial sextuality and most importantly DNA. He dreamed of achieving scientific glory through genetics and microbiology. Watson uses most of his time working and struggling with Francis Crick to create a DNA model. Him and Crick work well together even through some road blocks and bumps. Along the way Watson also works with Maurice Wilkins and Rosalind Franklin. Rosalind Franklin provides conflict because she has difficulty at first working and getting along with the others. This group of scientist navigates a new world of discoveries as they race other scientists to the DNA structure. They are motivated by this competition and they use the mistakes of the other scientist to their advantage. For example when they get hold of a draft of Pauling’s most recent breakthrough on DNA. They are shocked and disappointed to find out it looks as though he has cracked it, however it turns out he has made some very noticeable mistakes. The
Over break I decided to read The Double Helix by James D. Watson. This book was a fascinating memoir on the discovery of the double helix from the point of view by James Watson. I found his story fascinating due to the fact that in science classes we only see the discovery of what has happened. We never get to learn their story to how this discoveries were uncovered. This is the reason I believe that Watson wrote the story; to enlighten readers on the not so scientific pieces of a scientific discovery. The reader can see many different aspects of Watson’s life: such as relationships, how the discovery had impacted his life, and the time he spends in the lab. Firstly, lets take a look at some of Watson’s relationships.
Watson and Crick were able to figure out the pairs of nucleotides before Franklin was able to figure it out. This made sense that the base pairs are on the inside of the strands while the outside holds two sugar-phosphate strands. Watson and Crick, from looking at Rosalind’s research, were also able to conclude that DNA crystals could be flipped upside down and backwards, and still look the same meaning the backbone to the structure must be identical and that they run in opposite directions. If no one put all of the information together, we might not know everything about the structure of DNA that we know
He was in shock of Franklin’s discoveries about DNA and was going to look further into what she had said. Watson and another scientist, Francis Crick, soon concluded that the structure of DNA was a
Back From the Dead In 1953, two scientists discovered the formation of life, otherwise know as DNA. These scientists were named James Watson and Francis Crick and are now known as two of the most influential scientists in today's scientific community. Watson and Crick discovered the double helix shape of DNA. Thanks to Watson and Crick’s discovery the genetic discoveries and technology accelerated and are still accelerating at a fast rate.
In Time Magazine an article states On February 28 1953, James Watson and Francis Crick broke the DNA code and discovered that the DNA strand is double helix and forms like a ladder. They found that cytosine and guanine were paired together and that adenine and thymine were paired. They discovered the building block of life (Wright, 1999). DNA is found in all living organisms.
In 1953 four scientists: James Watson, Francis Crick, Maurice Wilkins and Rosalind Franklin completed a DNA model which they created using observed X-ray diffraction patterns. This model showed how the structure of DNA was able to transmit genetic information from parents to their offspring.
Rosalind Franklin’s work on DNA was crucial in discovering the composition of the human body as a whole. Her x-ray photo revealed a double helix structure and she also discovered the A and B form of DNA. She worked through the adversity of being a female in a predominately male dominated realm and made remarkable findings that were eventually stolen. She adapted to a new lab with antiquated technology. Before this discovery, the structure of DNA was thought to be simple. Scientist, Watson and Crick, started with the wrong structure of DNA from a misinterpretation of notes from one of Franklin’s presentations. Unlike Watson and Crick, Rosalind Franklin could explain DNA and how it worked.
The researcher’s experiment is almost entirely based on DNA (deoxyribonucleic acid), the relatively recently discovered molecule that “forms the molecular basis for heredity”. In specific, the project to be undertaken focuses on genes, specific sections of DNA, that are responsible for communicating to an organism “instructions for synthesizing every protein” an organism would require. In the middle of the nineteenth century, a large amount of scientists were involved in the search for the structure of the all-important DNA molecules. The official discovery was made in the year 1953, by James Watson, Francis Crick, and Maurice Wilkins.
