Can Biologists Rewrite the Genome’s Spaghetti Code?

# Can We Design Life Like We Design Machines? Scientists are getting better at editing and creating DNA, raising an exciting possibility: what if we could design new organisms the way engineers design buildings or cars? The big problem is that evolution has made genomes incredibly messy and interconnected—nothing like the clean, separate parts engineers prefer—so we're still far from being able to reliably create custom life forms on demand.
