I think that the most scientific discovery in history was probably the discovery of the structure of the DNA. It has a lot of science like how it looks like what it's made up of and a bunch of things that would take a long time for someone to find which it did. Roseline Franklin discovered the structure of the DNA and took a picture of it was the first picture ever taken of a cell and how DNA looked like. She discovered that it was in fact in a shape of a twisting ladder or a double helix. 

She also discovered that it was made up of thymine, and I can't really remember what else it was made up of, there should be a previous blog that tells us what DNA is made up of so if you can check it out. It was a pretty long time ago so it might be at the bottom or on the next blog page. Anyway she was copyrighted if that's the correct way to say things. Some people thought they found out what DNA looked like, but they were incorrect. They heard about Franklin and then they stole her evidence and the model she had built of DNA.
