| Abstract | Two forms of the Sendai virus P/C mRNA have been predicted: one an exact copy of the viral genome, and the other with a single G insertion within a run of three G's. We directly cloned the mRNA or portions of it containing the insertion site and screened the resulting colonies with oligonucleotides that could distinguish the presence of three or four G's at this position. We found that 31% of the mRNAs did in fact contain the predicted insertion, whereas the viral genomes contained no heterogeneity at this position. A smaller fraction (7%) of the mRNA contained two to eight G's inserted at this position. The insertions also took place during RNA synthesis in vitro with purified virions but were not detected when the mRNA was expressed in vivo via a vaccinia virus recombinant. When the Sendai virus- and vaccinia virus-derived P/C mRNAs were coexpressed in the same cells under conditions in which each could be distinguished, those from the Sendai genome were altered as before, but those from the vaccinia virus genome remained unaltered. The activity that alters the mRNA is therefore likely to be coded for by the virus and cannot function in trans. |

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.
