In multicellular organisms, DNA replication adapts to variations in growth conditions, DNA damage and chromatin organization changes associated with cell differentiation. Therefore, only a subset ...

A University of Sheffield study has provided a brand new insight into how our DNA can replicate itself. The team has captured "never before seen snapshots of enzymes trimming branched DNA after ...

Unexpected slowdowns or spikes in this signal were often interpreted as knots in DNA. But now, a new study published Aug. 12 ...

DNA stores all of the information necessary for life phenomena, and a cell transmits its own genetic information to two daughter cells through DNA replication and cell division. Replication stress ...

For DNA to replicate, the helix must first unwind and break the DNA from a double strand into two single strands. Upon binding, helicases melt the DNA, breaking the chemicals bonds holding the ...

DNA replication is closely linked to the process of cell division. Before a cell can divide into two daughter cells, it must ensure that each daughter cell receives an exact copy of the genetic ...

Cryogenic electron microscopy (cryo-EM) has enabled researchers to study how the DNA replication machinery assembles at sites where DNA is damaged.

DNA Day is held on April 25 to commemorate the publishing of the scientific papers that described the helical structure of the DNA molecule ...

A protein that prepares DNA for replication also prevents the replication process from running out of control, according to a new study. The work solves a mystery that has long puzzled biologists.

Plasmids, small circular DNA molecules found in bacteria, may contain antibiotic-resistance genes and have the ability to replicate independently. Bacteria can transfer these plasmids to one ...

How does embryonic DNA replicate and repeat? Embryonic cells need to divide, fast. But mess with their chromatin, and they’ll stall. Read more.
