Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

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 must be ...

When cells in the human body divide, they must first make accurate copies of their DNA. The DNA replication exercise is one of the most important processes in all living organisms and is fraught with ...

This animation reflects the contour of a sphere made of rings of DNA double helices connected together (staple strand crossovers are not shown here), using the Yan group’s new technique of DNA origami ...
