| Abstract | Retroposition is the copying of genetic information from one locus of the genome to another locus. This process involves reverse transcriptase, one of the most ancient cellular enzymes. All retroposition elements are divided into retrotransposons (that code reverse transcriptase) and retroposons (that do not code this enzyme). There are specialized families of retroposition elements that selectively copy themselves into certain compartments or loci of the genome and ignore other loci and compartments. Retroposition can form the basis for regulation of genomic processes. The following facts are in agreement with this suggestion. Retroposition elements are present in each genome. The families of retroposition elements that selectively copy themselves into certain compartments or loci of the genome and ignore other loci and compartments. Retroposition can form the basis for regulation of genomic processes. The following facts are in agreement with this suggestion. Retroposition elements are present in each genome. The families of retroposition elements develop more rapidly than the genome as a whole. Retropositions are of frequent occurrence. Integration of retroposition elements is a signal that triggers certain processes in the genome at the integration site. The data on a particular localization of retroposition elements in the genome agree with the suggestion discussed here. The processes of retroposition and pathology are probably interrelated. Trisomy of chromosome containing many retroposition elements can increase the activity of retroposition processes. The copying of retroposition elements into a locus containing the oligonucleotide repeat cluster may trigger the dynamic mutation. The revealed interlinear genomic polymorphism in the organization of the ID family in normotensive and hypertensive rats suggests the existence of additional copies of this element in the genome of spontaneously hypertensive rats. |

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.
