...capturing the shift in contemporary art from photography to video and back again. Exhibit A is Patricia Piccinini, mistress of the morph. For her wondrous meditations on genetic engineering, it's only natural that she has spawned a mutant medium. Here Piccinini is represented by her Venice Biennale video, Plasmid Region, 2003, which shows a magnified plasmid cell slowly reproducing. How to love her offspring, including her often photographed "siren mole," is a question her deeply disturbing work raises...
...resurrected diseases previously thought to have been eradicated or at least controlled, this is an alarming prospect. Imagine one of those bacteria in your gut happens to be strep or staph or tuberculosis—something nasty, but controllable with standard antibiotics. Now imagine that they pick up a plasmid from a genetically modified piece of corn. What happens? The antibiotics don’t work any more. At this point it might be worth buying some life insurance and making sure your will is in order...
...technology, in which they replicated specific genes by placing them in host cells grown in the laboratory. In 1983 scientists at the biotechnology company Amgen isolated the specific bit of DNA that carried the code for producing erythropoietin. They placed the gene in a minuscule bacterial structure called a plasmid, inserted the plasmid into the ovary of a hamster and began to produce synthetic erythropoietin. In 1989 the Food and Drug Administration approved the use of recombinant human erythropoietin under the name Epoetin alfa. The process has since saved thousands of lives...
...procedure, though the simplest available, might have been designed by Rube Goldberg. The luciferase gene was spliced to the regulatory switch of a gene belonging to a virus that infects plants. The altered two- part piece of DNA was then inserted into a circular strand of DNA, called a plasmid, from the bacterium Agrobacterium. The bacterial plasmid was incubated with tobacco-leaf cells, and the cells were nurtured into full-fledged plants...
