| Abstract | Cell cycle checkpoint activation and DNA repair pathways govern genomic stability after genotoxic stress. Genotoxic insult results in activation of an interwoven network of DNA damage checkpoints and DNA repair pathways. Post-translational modifications on a number of proteins involved in both checkpoint activation and DNA repair play an important role in this cellular response. Genotoxic stress can induce a wide variety of DNA lesions. Among these DNA alterations are double-stranded breaks and single-stranded DNA gaps. Repair of these DNA alterations requires damage recognition and resection. Here we discuss how DNA repair and DNA damage checkpoints cooperate and deal with DNA damage. Processing of DNA lesions by structure-specific nucleases results in DNA-protein intermediates, which form the basis for checkpoint activation and DNA repair. Post-translational modifications like phosphorylation and ubiquitination modulate the DNA damage response in a spatial and temporal manner. Cell cycle-dependent regulation additionally plays a key role in the regulation of both DNA repair and checkpoint activation. We highlight recent advances in in vivo imaging that greatly expand our knowledge on the relationships between DNA damage checkpoints and DNA repair. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
