| Abstract | We describe here the production of complex libraries enriched in sequences from each human chromosome type, starting with only a few thousand sorter-purified chromosomes. In this procedure, DNA is extracted from the sorted chromosomes, digested to completion by using the frequently cutting restriction endonuclease Sau3A1, and ligated, on each end, to an adaptor oligonucleotide. These fragments are then amplified using PCR with a sequence homologous to the adaptor oligonucleotide as a primer. We have used this procedure to produce PCR libraries for each of the 24 human chromosomes. These libraries were characterized by gel electrophoresis and found to be composed of a continuum of sequences ranging in size from a few hundred to approximately 1,000 bp. The libraries, when used as probes for fluorescence in situ hybridization, stained the target chromosomes more or less continuously, even after PCR amplification for more than 200 cycles. These libraries are useful as hybridization probes to facilitate molecular cytogenetic studies and as sources of probes either for identification of polymorphic short tandemly repeated sequences or for development of sequence-tagged sites. |

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.
