| Abstract | The protein (VPg) linked to the 5' termini of poliovirus RNAs resolved into two species when subjected to non-equilibrium electrofocusing. The differently charged forms of VPg were not due to protein phosphorylation nor to variability of the number of phosphate residues associated with the nucleotide moiety remaining after RNase digestion of the nucleoprotein. Single-stranded viral RNA isolated from mature virions contained predominantly the more basic form of VPg, whereas unpackaged single-stranded RNa remaining in cells at the end of the virus replication cycle contained predominantly the more acidic form of VPg. Replicative-form (RF) molecules also contained both species of VPg, with the more acidic form representing the major species. Both plus and minus RNA strands in RF had similar VPg compositions; however, there appeared to be a strongly selective loss of VPg from only the minus strand in RF, particularly at late times postinfection. |

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.
