High fidelity: Researcher finds keys to genome

Lesions in DNA can occur as often as 100,000 times per cell per day. They can be the result of normal metabolic activities, like free radicals, as well as exposure to environmental factors such as UV radiation, X-rays and chemical compounds. Researchers share a discovery that explains how cells use a process called replication fork reversal in order to deal with these roadblocks and transmit accurate genetic data.
