James Watson And Francis Crick And The Double Helix Summary

James Watson was born on April 6, 1928 in Chicago Illinois. He was a very gifted and bright child. He is most known for his contributions to DNA and Genetics along with his co-worker Francis Crick. Watson received his B.S. at the University of Chicago and received a Ph.D. from Indiana University. Watson also worked at the University of Cambridge's Cavendish Laboratory in England. This was where he first met Francis Crick. (Bagley).

This paper explores the history and some interesting facts about DNA. The last couple centuries have seen an exponential growth in our knowledge of DNA. The history of the DNA can be traced back to multiple devoted scientist. This article attempts to summarize, and review the basic history of DNA while providing some fascinating information about it.

In the early 1950s, the race to find the structure of DNA was in full swing. The search was being conducted at three different colleges. At the California Institute of Technology, Linus Pauling,

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.

2. What role did James Watson & Francis Crick play in our understanding of DNA’s structure? They discovered the 3D structure.

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?”

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

DNA, the molecule of life that carries genetic information in humans and almost all other organisms, has been considered as one of the greatest discoveries until now. If DNA could not have been discovered, we would not be able to do or test numerous things such as paternity test and pathological confirmation. There are four main scientists who contributed their lives, knowledge, and ambitions to find out the DNA double helix, a DNA molecule that has two strands winding around each other: James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin. Throughout historical backgrounds and environments, their discovery of

Watson and Crick’s paper discussed the discovery of the double helix in DNA. It included the angles created by the bonds between molecules that created the double helix nature of our DNA. In order to do such, they used Rosalind Franklin’s ‘Photo 51’ with hinted at the fact that our DNA was, in fact, a double helix. As a supplement to this photo, they made calculations based on numbers that described the x-ray crystallography from Franklin. The monoclinic unit cells that Crick saw in the DNA were the same as the ones he had found in horse haemoglobin from one of his previous studies confirming that DNA was made up of two matching strands that fit with one another.

It is a common misbelief that DNA was first discovered by Watson and Crick in 1953, but it was identified by a Swiss chemist Friedrich Meischer in 1869, not acknowledged much for his identification. But later on the Watson and Crick model of DNA was widely accepted and recognized. Meischer identified a substance while working on white blood cells of pus coated bandages. He used salt solution to find out the composition of WBCs. He noticed that a substance is separated from solution when he added salt in it. After that when he added alkali in it, the separated substance dissolved in it again. Meischer named this substance as “nuclein” .He discovered the hereditary material but unfortunately could not convince the scientific community about his findings. For many years scientists believed that protein is a substance which has stored

The work of these four people led to a complete restructuring of the beliefs of the scientific community regarding genetic information. Their initial word led to further work which encompassed their hypothesis of how DNA replicates itself. From this work came the modern technologies of DNA fingerprinting and sequencing.

Since the late 19th century, farmers began to realize that the heredity of crops and animals could be manipulated by using living organisms by cross breeding and creating hybrid crops. Then in 1954, the discovery of the structure of DNA, deoxyribonucleic acid, was developed.

Beginning in the mid 1800’s, Gregor Mendel discovered that hereditary factors determine an organism’s physical, chemical, and functional characteristics but would take many years before being accepted . Once Mendel’s work was rediscovered in the 1900s, scientists began to search for the molecule involved in inheritance that led to the discovery of deoxyribonucleic acid (DNA) the hereditary material present in the cells of all living organisms.

I decided to look more in to the topic of DNA. The main question of the article, The Structure of DNA: Cooperation and Competition was “How do living things pass on traits to their offspring?”. The conversation started in the 19th century when Gregor Mendel realized that there were patterns to a person’s traits but wasn’t sure how or what caused these patterns. It wasn’t until the middle of the 20th century that scientists were able to use new technology to discover that genetic code was carried on chromosomes. Through collaboration, four scientists, James Watson, Rosalind Franklin, Francis Crick and Maurice Wilkins worked in teams to figure out how this genetic code worked. Wilkins and Franklin, along with Raymond Gosling, used Xray technology

The scientific rules of genetics were not known until the nineteenth century, when Gregor Mendel determined from his study of plants that particles that can not be seen carry traits that are passed on from generation to generation. In 1953, James Watson and Francis Crick made the makeup of the genetic code called deoxyribonucleic acid, or DNA, the genetic material that is in all living cells. Deoxyribonucleic acid encodes the order of amino acids that have peptides and proteins. In the 1970s, researchers started experimenting with the transfer of a specific part of DNA from one organism to another, letting the other organism make a new protein and make a new trait. This scientific breakthrough led to the
