| Abstract | A search of databases with the sequence from the 5' untranslated region of a Hydra cDNA clone encoding a receptor protein-tyrosine kinase revealed that a number of Hydra cDNAs contain one of two different sequences at their 5' ends. This finding suggested the possibility that mRNAs in Hydra receive leader sequences by trans-splicing. This hypothesis was confirmed by the finding that the leader sequences are transcribed as parts of small RNAs encoded by genes located in the 5S rRNA clusters of Hydra. The two spliced leader (SL) RNAs (SL-A and -B) contain splice donor dinucleotides at the predicted positions, and genes that receive SLs contain splice acceptor dinucleotides at the predicted positions. Both of the SL RNAs are bound by antibody against trimethylguanosine, suggesting that they contain a trimethylguanosine cap. The predicted secondary structures of the Hydra SL RNAs show significant differences from the structures predicted for the SLs of other organisms. Messenger RNAs have been identified that can receive either SL-A or -B, although the impact of the two different SLs on the function of the mRNA is unknown. The presence and features of SL addition in the phylum Cnidaria raise interesting questions regarding the evolution of this process. |

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.
