Rosalind Franklin used X-ray crystallography to study the structure of DNA molecules. She was able to produce clear X-ray images of DNA molecules, which showed that it existed as a double helix.
Rosalind Franklin made important contributions to the understanding of the DNA double helix structure. She also helped to elucidate the role of DNA in heredity by showing that it does not exist in single-stranded form, as had been previously thought.
Franklin’s work on DNA was instrumental in the development of the field of molecular biology because it provided solid evidence for what had previously been only theoretical ideas about how genetic information is stored and passed on from one generation to another.
She also made significant contributions to the understanding of RNA and protein synthesis by showing that they are closely related chemically and structurally. This knowledge has allowed scientists to understand how certain proteins can be produced when there is an error in RNA production or processing, which can lead to diseases such as cancer or bipolar disorder.
Franklin’s work helped to lay the foundation for the discovery of the genetic code because she was able to show how nucleotides are arranged along double helixes according to certain rules that govern their formation into specific sequences within cells (or elsewhere).
