| Abstract | Exon/intron architecture varies across the eukaryotic kingdom with large introns and small exons the rule in vertebrates and the opposite in lower eukaryotes. To investigate the relationship between exon and intron size in pre-mRNA processing, internally expanded exons were placed in vertebrate genes with small and large introns. Both exon and intron size influenced splicing phenotype. Intron size dictated if large exons were efficiently recognized. When introns were large, large exons were skipped; when introns were small, the same large exons were included. Thus, large exons were incompatible for splicing if and only if they were flanked by large introns. Both intron and exon size became problematic at approximately 500 nt, although both exon and intron sequence influenced the size at which exons and introns failed to be recognized. These results indicate that present-day gene architecture reflects at least in part limitations on exon recognition. Furthermore, these results strengthen models that invoke pairing of splice sites during recognition of pre-mRNAs, and suggest that vertebrate consensus sequences support pairing across either introns or exons. |

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.
