| Abstract | cdc28, one of several genes required for cell division in the yeast Saccharomyces cerevisiae, has been isolated on recombinant plasmids. A recombinant plasmid pool containing the entire yeast genome was constructed by partial digestion of yeast DNA with the four-base recognition restriction endonuclease Sau3A to give the equivalent of random fragments, size selection on sucrose gradients, and introduction of the fragments into the yeast vector YRp7 by use of the homology of Sau3A ends with those generated in the vector by cleavage with BamHI. Recombinant plasmids capable of complementing cdc28 mutations were isolated by transformation of a cdc28ts strain and selection for clones capable of growth at the restrictive temperature. Plasmids responsible for complementing the cdc28ts phenotype were shown to recombine specifically with the chromosomal cdc28 locus, confirming the identity of the cloned sequences. In addition, one of the recombinant plasmids was capable of complementing a mutation in tyr1, a gene genetically linked to cdc28. This method of gene isolation and identification should be applicable to all yeast genes for which there are readily scorable mutants. |

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.
