A double-strand break (DSB) is a type of DNA damage where both strands of the DNA helix are cut or broken at the same location, causing a complete discontinuity in the DNA molecule. Unrepaired or ...
Cars patched up after a wreck may look fixed—but never run quite as before. The same may hold true for chromatin, according to a study published in Science on November 6. In response to double-strand ...

New study shows that in women with BRCA1 or BRCA2 mutations, their breast cells already carry a clear pattern of DNA “damage ...
BRCA1 and BRCA2 genes play a crucial role in repairing damaged DNA. Mutations in BRCA1 and BRCA2 substantially increase the likelihood of breast and ovarian cancer, respectively. This new research ...
Like base editing, prime editing offers a safer way to genome editing by relying on a nickase enzyme that “nicks” one DNA strand at a time, rather than cutting both simultaneously. Then, with the ...
