Double strand break repair model in biology - meaning, definition and examples

DNA, the blueprint of life, is constantly under threat from various sources, including radiation, chemical agents, and even normal cellular processes. One of the most severe forms of DNA damage is a double strand break (DSB), where both strands of the double helix are severed. If left unrepaired, DSBs can lead to genetic instability, cell death, or even cancer. Hence, cells have evolved intricate repair mechanisms to restore the integrity of the DNA molecule.
