    List key technologies enabling modern uses of biology

    Biotechnology is the use of biological agents for technological advancement. Biotechnology was used for breeding livestock and crops long before the scientific basis of these techniques was understood. Since the discovery of the structure of DNA in 1953, the field of biotechnology has grown rapidly through both academic research and private companies. The primary applications of this technology are in medicine (production of vaccines and antibiotics) and agriculture (genetic modification of crops, such as to increase nutrient content). Biotechnology also has many industrial applications, such as fermentation, the treatment of oil spills, and the production of biofuels (Figure 1).

    The left side of this image is an old black and white photo of a mailbox plastered with an advertisement reading “Penicillin cures gonorrhea in four hours. See your doctor today.” The right side of the image shows a petri dish streaked with bacteria. Bacteria grow everywhere on the plate except where discs containing antibiotic have been placed. These areas are completely devoid of bacterial growth
    Figure 1. Antibiotics are chemicals produced by fungi, bacteria, and other organisms that have antimicrobial properties. The first antibiotic discovered was penicillin. Antibiotics are now commercially produced and tested for their potential to inhibit bacterial growth.
