Answer:
- Ernest Everett Just was a pioneering biologist who performed research on the concept of fertilization. He developed the techniques used by the , molecular biologist later to understand the biochemistry of the DNA.
- In 1944 after the work of Avery, Erwin Chargaff started research related to the composition of the DNA molecule using ultraviolet spectroscopy and paper chromatography and found that the composition of DNA varies in different species but remains same in same species. He proposed that adenine equals to the thymine and the cytosine equals the guanine.
- Francis Crick was the person who with James Watson gave the helical structure of the DNA using X-ray crystallography.
They all helped society in understanding the DNA molecule and helped increase the knowledge about DNA.
