| Abstract | We have discovered a centrally located site that is required for efficient replication of bacteriophage Mu DNA and identified it as a strong DNA gyrase-binding site. Incubation of Mu DNA with gyrase and enoxacin revealed a cleavage site 18.1 kilobases from the left end of the 37.2-kilobase genome. Two observations indicate a role for the site in Mu replication: mutants of Mu, able to grow on an Escherichia coli gyrB host that does not allow growth of wild-type Mu, were found to possess single-base changes resulting in more efficient gyrase binding and cleavage at the site. Introduction of a 147-base-pair deletion that eliminated the site from a prophage inhibited the onset of Mu replication for greater than 1 hr after induction. |

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.
