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 ...
A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...
The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller ...
The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...
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 ...
Researchers have found that the way DNA is packaged in cells can directly impact how fast DNA itself is copied during cell division. They discovered that DNA packaging sends signals through an unusual ...
