| Abstract | When Bloom syndrome (BS) cells labeled with bromodeoxyuridine (BrdUrd) for one round of DNA replication were fused with nonlabeled normal cells, the hybrid cells had a normal level of sister chromatid exchange (SCE) at the first mitosis after fusion. However, when normal cells treated with mitomycin C (MC) were fused with nontreated normal cells, the MC-induced SCE was not affected by fusion with normal cells. Single and twin SCEs were analyzed in the Colcemid-induced endoreduplicated normal and BS lymphoid B cells from diplochromosomes. In normal cells, the same number of SCEs occurs in each of the two cell cycles; the SCE ratio of single (6.30 SCEs per cell) to twin (2.92 SCEs per cell) was 2:1 on the endoreduplicated-cell basis, showing 1:1 on the diploid-cell basis. In BS cells, the SCE ratio of single (144.8 SCEs per cell) to twin (5.9 SCEs per cell) was 25:1 on the endoreduplicated-cell basis and was 12:1 on the diploid-cell basis. These studies strongly suggest that most of the BS SCEs occur during the second cell cycle when BrdUrd-containing DNA is used as template for replication and that the normal level of BS SCE observed at the first mitosis of the hybrid cells is the result of SCE inhibition resulting from the fusion with normal cells. |

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.
