Between 1869 when the molecule was discovered and 1953, when its molecular structure was identified.
Rosalind Franklin did not discover DNA. DNA was discovered long before she photographed the images via X-ray crystallography. With the help of these images, Watson and Crick were able to figure out the structure of the nucleic acid in 1953. Watson and Crick did not discover DNA either; they developed the concept of the "double helix," which was accepted as the structure of DNA.
X-ray crystallography.
The research of Rosalind Elsie Franklin led to the discovery of the double-helix structure of DNA. She did not actually discover DNA, but opened the way for others. She died in 1958, four years before the Nobel Prize in chemistry was awarded to her colleagues Maurice Wilkins, James Watson and Francis Crick for the discovery of the structure of DNA.
Gregor Mendel did not discover DNA; instead, he is known as the "father of modern genetics" for his work on inheritance in pea plants, which laid the foundation for understanding the basic principles of heredity. The discovery of the structure of DNA is credited to James Watson and Francis Crick in 1953.
Radioactively tagged bacteriophages are used to confirm that DNA, not protein, is injected into host cells during infection. The radioactively labeled DNA can be detected inside the host cells after infection, providing evidence that DNA is the genetic material transferred by the bacteriophages. This experiment was crucial in establishing DNA as the genetic material in organisms.
The person who helped discover the shape of DNA is James Watson, along with Francis Crick.
