The Double Helix Case Study

763 Words 4 Pages
1. Using Rosalind Franklin’s X-ray pictures James and Francis redeveloped the Watson - Crick Model that shows that a DNA molecule forms a double-helix. Together they hypothesised that if the strands were separated lose floating nucleotides would attach to their complimentary nitrogenous bases forming a template, which is the process of DNA replication. Their findings were published in the scientific nature journal April 1953. Crick had made an important discovery to the understanding of protein synthesis by showing evidence that 3 grouped bases determined the type of Amino Acids formed.

b. Rosalind Franklin was a famous chemist she gave crick and Watson the solution to their model by producing X-ray diffraction pictures showing that DNA was

Using his knowledge of DNA pursued a project to locate the genes and to identify the sequences of the nitrogen bases pairs in the human genome.

2. Rosalind Franklin’s personality was the reason she became a scientist in the first place when she was young she did math for fun. John Desmond Bernal proclaimed in acknowledgment that franklin worked towards perfection and clarity, he said that her photos were one of the most beautiful X-ray photos taken of substance. She excelled in everything maths and Science when she worked on something she was in charge mentioned by (Bagley M, 2013)
Francis Crick became friends with James D Watson a student much younger then he was this friendship that was built to progress in the research of DNA was one example of how Crick had the ability to make productive friendships with other

DNA molecules carry hereditary information from one generation to the next this understanding has opened doors to Genetic engineering; heredity which has allowed Biochemists to create Protein molecules (Fetzer S, 2008)As your DNA stores genetic information it has made it easy for early cancer and other sickness detections. Drugs can be custom made and this understanding helps with the new development of diagnoses according to (Murnaghan I, 2018).There is an important impact in children’s lives with paternity information because it has made it easy to find child’s actual parents it can also help with telling people if their children will have mutations because of their genes. There has been a change in Agriculture for the better because treatments can be made for animals to stop and prevent diseases which increases and improves resources. It is also important for us to know the Structure of DNA so we can implement the technologies and practical
