So it is basically like it is basically like this is over one strand and this is another strand. This X-ray diffraction picture of a DNA molecule was Watsons inspiration (the pattern was clearly a helix). So two strands which are anti parallel to each other, anti Beller to each other. This is the iconic X-ray diffraction photograph of DNA taken by physical chemist Rosalind Elsie Franklin and PhD student Raymond G.

Double helical structure and It is composed of two pollen nucleotide strands. The most famous X-ray photograph, Photo 51, is still printed in most Biology textbooks. So which states that which states that DNA is a double helical structure. Rosalind Franklin, from the Kings College team, made an X-ray diffraction image of DNA, which is known as Photograph 51. Rosalind Franklin's X-ray diffraction patterns of DNA molecules rendered the important clue that DNA has the structure of a double helix. And other than that we know that the structure of DNA was found out by the Watson and Crick Watson and Crick model that we have studied so many times Watson and Crick model.

So this is the basic information about the DNA. And we know that this DNA is concentrated in the nucleus and in the chromosome inda chromosome. Because they have are any they have are any as genetic material. DNA is the genetic material and it is found in almost every organism except the virus except the virus. Rosalind Franklin's X-ray diffraction patterns of DNA molecules rendered the important clue that DNA has the structure of a double helix. So we know that DNA is the genetic material. And Watson and Crick used X ray for helical structure and franklin formulated double stranger structure. So they're an experiment for the structure then is they used X ray diffraction to find helical nature franklin formulated double stranded. Her x-ray crystal diffraction micrographs defined DNA. They employed X ray diffraction to understand the storage of DNA. Rosalind Franklin set Watson and Crick on the right path so their clever guesswork could succeed. So first is that franklin used X ray to determine the helical nature and the Watson and Crick formulated double standard structure. And they have given us different options regarding data. The discovery of the structure of DNA in 1953 was made possible by Dr Rosalind Franklins X-ray diffraction work at Kings. First, she minimized how much the X-rays scattered off the air surrounding thecrystal by pumping hydrogen gas around the crystal. There were three scientists involved franklin wasn't and creek. By improving her methods of collecting DNA X-ray diffraction images, Franklin obtained Photo 51 from an X-ray crystallographyexperiment she conducted on. Hello students for today's question is about the contribution to the success of DNA.
