history of dna timeline DNA the molecule of heredity lies at the heart of all living organisms that we know of today But considering its fundamental nature it is curious that we owe the original discovery of this substance to such a thankless task as analysing pus from the bandages of hospital patients
Explore the milestones and controversies of DNA research from the discovery of its structure to the latest applications in biotechnology and medicine The history of DNA started as early as 5000 BC when humans began the practice of selective breeding to produce more robust crops and livestock

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 The structure of DNA unlocked the door to understanding many aspects of DNA s function such as how it was copied and how the information it carried was used by the cell to make proteins As we ll see in upcoming articles and videos Watson and Crick s model ushered in a new era of discovery in molecular biology
In Summary The History of DNA 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 Avery MacLeod and McCarty proved The history of genetics can be represented on a timeline of events from the earliest work in the 1850s to the DNA era starting in the 1940s and the genomics era beginning in the 1970s

Discovery DNA Isolated Frederick Miescher isolates DNA from cells for the first time and calls it nuclein 1879 Discovery Mitosis Described Walter Flemming describes chromosome behavior during animal cell division He stains chromosomes to observe them clearly and describes the whole process of mitosis in 1882 Rediscovery of Mendel s work The discovery in 1953 of the double helix the twisted ladder structure of deoxyribonucleic acid DNA by James Watson and Francis Crick marked a milestone in the history of science and gave rise to modern molecular biology which is largely concerned with understanding how genes control the chemical processes within cells
