I think that the greatest discovery in science was the discovery of DNA. As you all know, DNA was never known back then. One day a person named Rosalind Franklin heard of DNA and wanted to discover what it was. She used her x-ray diffraction system to help her in her experiments to find DNA. One day she had a clear photo of DNA which she called Photo 51.
She also discovered two types of DNA, which she called A and B. If she had never discovered DNA, then we would know anything about ourselves. DNA contains genetic information about yourself. It contains you eye color, your height, and many more things. Then two guys named Francis Crick and James Watson made a model of DNA. They said DNA looked like a twisted ladder, and that was the model they made.
Some people consider the discovery of DNA the greatest discovery in scientific history.
