| Abstract | Dimethyl sulfoxide-induced Friend cells were labeled for periods of 5-60 min. The denatured RNA was fractionated by sucrose gradient centrifugation and the distribution of alpha- and beta-globin-specific [(3)H]RNA was determined by hybridization to hybrid plasmids containing mouse alpha- and beta-globin DNA, respectively. After 5 min of labeling, a 15S peak of beta-globin-specific (but not alpha-globin-specific) [(3)H]RNA was detected, next to an equal amount of 10S beta-globin [(3)H]RNA. With increasing periods of labeling, the amount of 15S beta-globin [(3)H]RNA remained constant but the amount 10S beta-globin [(3)H]RNA increased steadily. alpha-Globin-specific [(3)H]RNA sedimented at 11 S after 5 min of labeling and at 9.5 S after longer labeling periods. Analysis of 15S globin-specific [(3)H]RNA purified by the poly(dC)-cDNA method [Curtis, P. J. & Weissmann, C. (1976) J. Mol. Biol. 106, 1061-1075] showed oligonucleotides characteristic of beta-globin mRNA but not of alpha-globin mRNA, as well as about 20 new oligonucleotides. Our results suggest that 10S beta-globin mRNA arises via a 15S precursor that has a half-life of 5 min or less; 9.5S alpha-globin mRNA may be derived from an 11S precursor. |

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.
