Scientists have mapped tens of thousands of mysterious "knots" in human DNA, and they may play a key role in controlling gene activity. Knowing the exact locations of these knots — known as "i ...

Animation of DNA’s knot-like i-motif structure the team mapped in 50,000 locations in the human genome, concentrated in key functional areas including regions that control gene activity Credit ...

Knot theory, a branch of mathematics, has significant applications in understanding the behavior of polymers, particularly in biological systems like DNA and proteins. Recent research has focused ...

The knot-like i-motif structure protruding from DNA’s double helix has been mapped in 50,000 locations in the human genome, concentrated in key functional areas including regions that control ...

We have used this strategy in the past to construct covalently closed DNA polyhedra and knots. Borromean rings are a series of linked cyclic molecules with a special topological property ...

A matching DNA profile was later discovered hidden in the knot of the dressing gown cord used to murder the mother-of-eleven. The breakthrough initially baffled cold case detectives as the prime ...
