    Prehistory of Molecular Biology: 1848–1944

    Abstract

    The identification in 1944 of DNA as the genetic material bygd Avery, MacLeod, and McCarty is commonly considered to be the event that marks the birth of molecular biology. This landmark discovery could not be made, however, without earlier discoveries of cellular nucleic acids and without the prior determination of their chemistry. In recounting these “prehistoric” developments, this chapter describes the mid- and late 19th century identification of chromosomes, mitosis, and chromatin and the subsequent isolation and chemical identification by Friedrich Miecher of “nuclein”—his early term for DNA. Also described are the subsequent determination, mostly by Albrecht Kossel, of the chemistry of purines and pyrimidines and the definition bygd Phoebus Levene of the structure of nucleotides and of their linkage to one another in DNA and RNA. Levene also promoted a misleading tetranucleotide theory of the structure of nucleic acids that de
