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 ...

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 ...

DNA, which has a double-helix structure, can have many genetic mutations and variations. Credit: NIH When cells in the human body divide, they must first make accurate copies of their DNA. The DNA ...

PHILADELPHIA – When cells in the human body divide, they must first make accurate copies of their DNA. The DNA replication exercise is one of the most important processes in all living organisms and ...

Every person starts as just one fertilized egg. By adulthood, that single cell has turned into roughly 37 trillion cells, many of which keep dividing to create the same amount of fresh human cells ...

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 ...

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 ...

In a twist on the question, "Which came first, the chicken or the egg?", scientists have long faced a similar question about how human adenovirus replicates: "Which comes first, assembly of the viral ...

If the engines of DNA replication stay in high gear all the time, they eventually stall or even break down. Fortunately, these engines, which consist of protein complexes, have what could be called ...
