Computer model unravels knotty problems in DNA


October 4, 2017

If you've ever tried to untangle a pair of earbuds, you'll understand how loops and cords can get twisted up. DNA can get tangled in the same way and in some cases, has to be cut and reconnected to resolve the knots. Now, a team of mathematicians, biologists and computer scientists has unraveled how E. coli bacteria can unlink tangled DNA by a local reconnection process. The math behind the research could have implications far beyond biology. Full Story

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2017, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards.
