   Feb 28, 2021 · Modern understandings of DNA have evolved from the discovery of nucleic acid to the development of the double-helix model. In the 1860s, Friedrich Miescher (Figure 1), a physician by profession, was the first person to isolate phosphate-rich chemicals from white blood cells or leukocytes.

   Why was DNA first isolated from white blood cells?

   • DNA was first isolated from white blood cells by Friedrich Miescher, who called it nuclein because it was isolated from nuclei. Frederick Griffith’s experiments with strains of Streptococcus pneumoniae provided the first hint that DNA may be the transforming principle.

   Who discovered nucleic acids?

   • Friedrich Miescher (1844–1895) discovered nucleic acids. Modern understandings of DNA have evolved from the discovery of nucleic acid to the development of the double-helix model. In the 1860s, Friedrich Miescher (Figure 1), a physician by profession, was the first person to isolate phosphate-rich chemicals from white blood cells or leukocytes.

   • In the 1860s, Friedrich Miescher (Figure 1), a physician by profession, was the first person to isolate phosphate-rich chemicals from white blood cells or leukocytes. He named these chemicals (which would eventually be known as RNA and DNA) nuclein because they were isolated from the nuclei of the cells.

   Why is DNA a molecule?

   • DNA achieves this feat of storing, coding and transferring biological information though its unique structure. DNA is the molecule that holds the instructions for growth and development in every living thing. Its structure is described as a double-stranded helix held together by complementary base pairs. The basic units of DNA are nucleotides.

   How did Avery and MacLeod prove that DNA is necessary?

   • Avery, MacLeod, and McCarty proved that DNA is required for the transformation of bacteria. Later experiments by Hershey and Chase using bacteriophage T2 proved that DNA is the genetic material. Chargaff found that the ratio of A = T and C = G, and that the percentage content of A, T, G, and C is different for different species.
