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 ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

A new model offers a possible solution to the scientific question of why neutral sequences, sometimes referred to as 'junk DNA', are not eliminated from the genome of living creatures in nature and ...

Researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer. Every day, billions of cells in your body ...

The genes of great white sharks defy scientific explanation. An animal's genome can be deeply revealing, but ever since researchers started decoding great white shark (Carcharodon carcharias) DNA more ...

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 ...
