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 ...

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 ...

MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...
