195 1 year, British female doctor Franklin discovered the spiral structure of DNA from her X-ray diffraction photos. After research, she boldly put forward a hypothesis and gave a wonderful speech on it.

However, many people question her findings, the authenticity of her photos and the reliability of her assumptions. Under these pressures, Franklin also began to doubt himself: as an ordinary doctor, it may be a bit too much for him to ask such profound theoretical questions. She wavered. Therefore, she publicly denied her hypothesis and did not continue her research. Later, two other scientists made great achievements in this field and won the Nobel Prize in Medicine. However, their original research paper on DNA structure was published in 1953, which was two years later than Franklin's discovery.
