By fitting DNA into an engineering template,
the messy field of biology emerges as a complex but somewhat predictable system — one that synthetic biologists have begun to maneuver in recent years.
This major discovery resolves a heated debate in the
field, as it finally answers a question that has been discussed in
biology for over a century: Before dividing in two, DNA in a cell is comparable with spaghetti — a
messy mixture
of intermingled strands.
