| Abstract | Complementation of the repair defect in hamster xrs mutants has been achieved by transfer of human chromosome 2 using the method of microcell-mediated chromosome transfer. The xrs mutants belong to ionizing radiation complementation group 5, are highly sensitive to ionizing radiation, and have an impaired ability to rejoin radiation-induced DNA double-strand breaks. Both phenotypes were corrected by chromosome 2, although the correction of radiation sensitivity was only partial. Complementation was achieved in two members of this complementation group, xrs6 and XR-V15B, derived independently from the CHO and V79 cell lines, respectively. The presence of human chromosome 2 in complemented clones was examined cytogenetically and by PCR analysis with primers directed at a human-specific long interspersed repetitive sequence or chromosome 2-specific genes. Complementation was observed in 25/27 hybrids, one of which contained only the q arm of chromosome 2. The two noncomplementing hybrids were missing segments of chromosome 2. The use of a back-selection system enabled the isolation of clones that had lost the human chromosome and these regained radiation sensitivity. Transfer of several other human chromosomes did not result in complementation of the repair defect in XR-V15B. These data show that the gene defective in xrs cells, XRCC5, which is involved in double-strand break rejoining, is located on human chromosome 2q. |

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.
