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 ...
Like the human immune system, bacteria learn from past infections. CRISPR sequences—short snippets of DNA from previous viruses—guide destructive enzymes towards invading bacteriophages that express ...
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 ...
