For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event ...

During DNA replication, special enzymes move up along the DNA ladder, unzipping the molecule as it moves along. New nucleotides move in to each side of the unzipped ladder. The bases on these ...

Watson and Crick's discovery of DNA structure in 1953 revealed a possible mechanism for DNA replication. So why didn't Meselson and Stahl finally explain this mechanism until 1958 ...

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 ...

The replication fork is more than just a means for DNA duplication. It is connected to a checkpoint system that keeps the genome intact and prevents cancer. Aa Aa Aa Eukaryotic genomes are ...

Scientists have captured the first detailed 'molecular movie' showing DNA being unzipped at the atomic level -- revealing how cells begin the crucial process of copying their genetic material.

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