Concepts definition 1/7 What is meant by biotechnology ? • Broadest definitions vs. narrowest definitions of biotechnology A common understanding of biotechnology is needed... Society should decide what to "choose" biotechnology to mean as a basic to cope with social, communication, political and legislative matters 9
Concepts definition 2/7 Origin of the term “ Biotechnology ” According to Robert Bud (Science Museum London, UK) … The term « Biotechnology » was first used by Karl Ereky in 1919 in a book called " Biotechnology of Meat, Fat and Milk Production in an Agricultural Large-Scale Farm » Source : ROBERT BUD, History of 'biotechnology' Karl Ereky Nature 337 , 10 (05 January 1989) 10
Concepts definition 3/7 Origin of the term “ Biotechnology ” For Ereky The term “Biotechnology" indicated the process by which raw materials could be biologically upgraded into socially useful products … Source : The evolution of the word ‘biotechnology’ Max J.

Concepts definition 4/7 Biotechnology: Broad definition FDA's working definition of biotechnology is “ the application of biological systems and organisms to technical and industrial processes ”. This definition takes : • Both the "old" and "new" science age-old techniques and most advanced uses of recombinant DNA technology. • Many applications … 12
Concepts definition 5/7 Biotechnology: Narrower definition The [direct] manipulation of nature for the benefit of mankind at the subcellular and molecular levels. Biotechnology at the Hebrew University (1992) Biotechnology: Narrowest "New" biotechnology is the industrial use of recombinant DNA, cell diffusion and novel bioprocessing techniques.

History & Evolution of Biotechnology 9/9 Stages of Biotechnology Modern Biotechnology The Second World War is considered a major crisis that has led to scientific discoveries : very crucial discoveries were reported, which paved the path for modern biotechnology and to its current status. In 1953, JD Watson and FHC Crick for the first time cleared the mysteries around the DNA as a genetic material, by giving a structural model of DNA known as “Double Helix Model of DNA” . 24
