What Gene Splicing Can Do For The Lowly Seaweed

Over the past decade, gene splicers have slipped new DNA into bacteria, tomatoes, and even humans. Now they've engineered a slimier form of life: seaweed. A team led by plant geneticist Subhash C. Minocha at the University of New Hampshire has transferred a marker gene into two species of the briny plants. The method, which took two years to perfect, involves using electricity to open holes in the membranes of seaweed cells just big enough for molecules of DNA to slide through.
