Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies ...

Previous researches on DNA included topics of bases, base-pairing, hydrogen bonds, structure, base sequence, dynamics, ...

Exactly how does the DNA replication process start? USC scientists provide the first snapshot of how double-helix DNA begins to unwind and replicate after certain proteins put on the “squeeze.” A ring ...

Life depends on double-stranded DNA unwinding and separating into single strands that can be copied for cell division. Scientists have determined at atomic resolution the structure of machinery that ...

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 ...

In two separate papers appearing in Proceedings of the National Academy of Sciences, Weninger and Erie looked at both human and bacterial DNA to gain a clearer temporal and structural picture of what ...

Researchers have revealed the structural mechanisms of a major DNA repair pathway in human cells. The research, published today as a Reviewed Preprint in eLife, is described by the editors as a ...
