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

Scientists have provided the most detailed account yet of the earliest stages of DNA replication, an essential process for ...

“The conventional thinking has been that single-stranded DNA breaks from PARPi ultimately generated DNA double-strand breaks, and that was what was killing the BRCA mutant cancer cells,” said Dr.

In a study published in Nature, researchers report the successful in vitro reconstitution of meiotic DNA double-strand breaks (DSBs) formation. Meiosis, a specialized form of cell division in most ...

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 ...
