Our current understanding of DNA began with the discovery of nucleic acids followed by the development of the double-helix model. In the 1860s, Friedrich Miescher (Figure 1), a physician by profession, isolated phosphate-rich chemicals from white blood cells (leukocytes). He named these chemicals (which would eventually be known as DNA) nuclein ...Later discoveries further confirmed and solidified the role of the cell in heredity, such as James Watson and Francis Crick’s studies on the structure of DNA. The discovery of the cell continued to impact science one hundred years later, with the discovery of stem cells, the undifferentiated cells that have yet to develop into more ...Talk Overview.
