Errors in DNA repaired
{"Image DocumentName": "Errors in DNA repaired", "Image ImageDescription": "DNA must be faithfully maintained, yet replication is not perfectly accurate and DNA is subject to damage by chemicals and other environmental agents. Cells have three mechanisms for DNA repair: Proofreading corrects errors in replication as DNA polymerase makes them. Mismatch repair scans DNA immediately after replication and corrects any base pairing. Excision repair removes abnormal bases that have formed because of chemical damage and replaces them with functional ones. \u00a9 2012 Pearson Education, Inc.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
