Researchers have uncovered a way to manipulate DNA at the atomic level using electric field gradients to control nitrogen ...

If you are using a ruler and compass to draw something - for example, a perpendicular bisector of a line or bisecting an angle - make sure you clearly show the compass arcs in your construction.

the principal axis either aligns with or is nearly perpendicular to the bisector of the bonds. The four bases adenine, guanine, cytosine, and thymine have different orientations. Additionally ...

In the former case, the principal axis is always perpendicular to the base plane, while in the latter, the principal axis either aligns with the bisector of the bonds or is close to perpendicular to ...

Three simple end treatments are supported, "flat" (the default), "round" and "pointed". The "flat" treatment cuts off the ends perpendicular to the path and the "round" treatment applies a semicircle ...
