How Did Rosalind Franklin Discover The Double Helix

Understanding DNA can take a lot of studying and confusion to even get the general idea of the concept. The structure of DNA is very complicated and complex to understand, but researchers James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin all developed the idea of the DNA structure in 1953. Deoxyribonucleic Acid is found in the nucleus of the cell. It is a double stranded molecule that contains the genetic code and is the main component of chromosomes. DNA is the blueprint of organisms. Nucleotides are the basic unit of DNA and they are made up of sugar, phosphate, and one of the four basis including adenine,

While at King's, Rosalind discovered much about DNA. Working with her graduate student, Raymond Gosling, she took the X-ray photographs that would eventually lead to the helix theory of DNA. But she also made other key discoveries. First, she determined that DNA was found in two distinct forms, the "wet" and "dry" forms. Gosling had photographed the dry

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.

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.

1. What role did Rosalyn Franklin play in our understanding of DNA’s structure? She discovered the double-helix position of the DNA.

I believe that Rosalind Franklin deserved more credit than she got foe her X-ray crystallography. Watson took photo 51 from her file without ther knowledge which showed that DNA has a definite pattern and two strands. Watson and Crick used the photo for their own personal gain instead of giving Rosalind any credit they saw Rosalind as below them so they had no issue stealing her idea.

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.

Also he helped with mapping cancer to help people or warn others, so they will be able to find if they have it. James helped out everyone on this planet and those who are sick or are sick but don’t know it. To be recognized in the scientific community you have to do something amazing. Crick and James Watson's first look toward taking in the structure of DNA missed the goal, but their second look took place in the spring 1953 and brought about the match of the ladder helical look. Which takes after a stepping stool. Their model added how the DNA particle could copy itself. Watson and Crick had looked the work of English scientist Rosalind Franklin, a partner of Maurice Wilkins' at King's College London, to land at their noteworthy disclosure, notwithstanding, her commitment to their discoveries would go generally unrecognized until after her she died. Franklin had made a few unpublished working papers talking about the basic characteristics of DNA, and with her understudy Raymond Gosling had taken a X-ray diffraction picture of DNA, known as Photo 51, which would get to be urgent proof in recognizing the structure of

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

Rosalind Franklin was born in 1920 in London, England and earned a Ph.D. in physical chemistry from Cambridge University. She learned crystallography (The science of determining the arrangement of atoms) and X-ray diffraction, techniques that she applied to DNA fibers. One of her photographs provided key insights into DNA structure, the double helix. Other scientists used it as the basis for their DNA model and took credit for the discovery. Franklin died of ovarian cancer in 1958, at age 37.

Scientist in early 1950s James Watson a biologist from Indiana University and Francis Crick a physicist were working at lab to discover the structure of DNA. The primary technique for structural analysis of biological molecules is X-rays. The wave length of X-ray is about the same as the space between the atoms in crystal matters. We learn and know that genetic information was carried on chromosomes made up of DNA and protein. Maurice decided and taken the first x-ray picture of DNA that lead him to suggest the DNA structure might be a helix. Watson was able to rely on Wilkins' research. If he had not, he may have not been the one to discover the structure of DNA. The biggest thing I learned from my research is that scientists can’t make discoveries

Using Rosalind Franklin’s photo, Watson, Crick, and Wilkins figured out the correct structure of DNA, which they published in the paper. Franklin also published an article in the same issue, providing further details on DNA's structure but he stole it. Franklin's image of the DNA molecule was the reason Watson, Crick, and Wilkins were

This story starts May 1, 1992. Rosalind Franklin is responsible for photo 51, a remarkable photo of DNA taken with x-rays. It was a top view of a strand of DNA. Watson used this picture to write a book called, The Double Helix. In the book he cast Franklin as an evil spirited women, but this is the opposite of what she was actually like. Many scientist objected to Watson’s book and one even questioned, “Did you even say she died?” To start the film they talk about how the Franklin family was wealthy, and full of philanthropist. Also from an early age she loved arithmetic and memory games. She went ot St. Paul girls school (school to prepare girls for a career), then finishes year early gets scholarship to go to Cambridge school. About this time the Nazi were on the march. She graduates

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.
