Researchers have identified a molecular brake that limits DNA replication in healthy cells, revealing how cells prevent a long-suspected replication catastrophe and pointing to a potential ...

Johns Hopkins Kimmel Cancer Center scientists report data from a new study providing evidence that random, unpredictable DNA copying "mistakes" account for nearly two-thirds of the mutations that ...

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 ...

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 ...

Real image of DNA molecules being copied in human cells, visualized by immunofluorescence microscopy. The yellow arrows mark where replication begins, and the white arrows indicate the direction in ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions, it can temporarily fold ...

Every time a cell divides, its DNA is duplicated so that the two daughter cells have the same genetic material as their parent. This means that millions of times a day a biochemical wonder takes place ...

Scientists at the University of Leicester have captured the first detailed "molecular movie" showing DNA being unzipped at the atomic level – revealing how cells begin the crucial process of copying ...

MOST cancers are caused by random mistakes in the genetic code that occur when cells divide, new research has shown. Share Article The findings challenge the widespread view that cancer mutations are ...

DNA is often described as the instruction manual for building the fundamental components of life. Proteins are helpers that ...
