DNA, it makes everyone special and unique. Throughout time, scientists have discovered many things about DNA. One such discovery the pairing of adenine-thymine and guanine-cytosine, but what about the structure? Watson and Crick are acknowledged the most for discovering and contributing the most to the structure of DNA in eighteen months; but what about Franklin? Though Watson and Crick are known for discovering DNA’s structure, Rosalind Franklin contributed the most to finding the structure of DNA because she was the first to take pictures of DNA’s B form, discover phosphate on is on the outside of DNA, and debunk DNA is antiparallel.
First, Franklin took a picture of DNA’s B form. That photo was acquired through Franklin bundling super …show more content…
She discovered phosphates are on the outside of the DNA strands. The phosphates are on the outside so that the phosphate-phosphate interhelical bonds are disrupted by water. Also, the hydrophilic phosphates caused the molecule to soak up water and lengthen causing the wet DNA to produce a sharp diffraction picture that resembled the pattern of a x; further proving phosphates are on the outside. Through Franklin’s research, phosphates were discovered to be on the outside of DNA strands which allowed other information to be put in place; such as nitrogenous bases and sugar. Franklin opened a passageway for Watson and Crick to further more their own discovery. In addition to finding phosphates are placed on the outside of DNA strands; Franklin also discovered DNA is …show more content…
People may believe this because Watson and Crick did end up constructing a model of DNA’s structure. Watson and Crick determined how the nitrogenous bases, sugars, and phosphates are placed on the DNA strand. However, if they did not obtain Franklin’s own discoveries they would have never correctly built a model of DNA’s structure. Franklin proved a photo that showed the double helix structure, the antiparallel lines, and the phosphates on the outside of the the DNA strand.Watson and Crick used Franklin’s discoveries but never acknowledged her in the paper. Therefore, without Franklin, Watson and Crick would have never built a proper model of DNA’s structure within eighteen months and not have discovered the correct structure of
