An anonymous reader writes "Forbes has a story on 'the biggest piece of artificial DNA ever made'. The real story is that companies are racing to produce longer and longer DNA fragments to serve the growing science of synthetic biology."
From the article: "On a piece of DNA as long as the one made for Microbia, ten or more genes may be present. By studying more than one gene at once, researchers hope to get a better picture of how they work in concert to produce an organism. Another advantage: These stretches can also be made to contain all the DNA letters that occur between genes. Scientists once thought of that stuff as junk, but many now believe it may regulate how the genes work or provide some other function."
