DNA replication is a fundamental process for a cell to ensure that an accurate copy of its genetic material is transmitted to daughter cells at each cell division. Challenges to DNA replication ...

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 ...

For years, scientists have puzzled over what prompts the intertwined double-helix DNA to open its two strands and then start replication. Knowing this could be the key to understanding how organisms - ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

As cells divide, they must copy all of their chromosomes once and only once, or chaos would ensue. How do they do it? By Amber Dance/Knowable Magazine Published Jul 7, 2023 6:00 PM EDT This article ...

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 ...

Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...
