Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

DNA polymerases are the “Xerox machines” that replicate our DNA. They must work with great precision to keep errors from creeping into our genes. In spite of this precision, they still accept building ...

A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues, the ...

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 ...

Every day, billions of cells in your body divide, helping to replace old and injured cells with new ones. And each time this happens, your entire genetic library — your genome, which totals more than ...

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 ...

Mitochondrial deoxyribonucleic acid (mtDNA) plays a crucial role in energy production and abnormalities in mtDNA are linked to various diseases. However, its regulatory mechanism remains ...
