A structure is a 3D shape made from different materials and parts. Some can be simple to build, such as a wall. Others can be complex, or harder to build, such as a bridge or a building.

Here we report the structure of an engineered replication terminator protein (RTP) of Bacillus subtilis in complex with a 21 base pair DNA by X-ray crystallography at 2.5 Å resolution.

A meron is a topological structure where the direction of the ... is not limited to meron pairs and can be applied to other complex surface plasmon polariton fields. Understanding these fields ...
