What mechanism for DNA repair may lead to new cancer treatments :hmn
Our DNA is under attack. Every day, around 55,000 single-strand breaks (SSBs) appear in the strands making up DNA helices in individual cells. When polymerases, molecules that replicate DNA strands, try to make new helices from strands with breaks in them, they can break the helix, creating what’s known as a single-ended double-stranded break (seDSB). …
