| Abstract | Synaptonemal complexes (SCs) are intranuclear structures that facilitate the reversible lateral synapsis of homologous chromosomes in the course of meiosis. It is still unclear which DNA nucleotide sequences are responsible for the attachment of chromatin to SC lateral elements. Considering the features of the dispersed repeated sequences (RSs), it is possible to assume that they participate in the structure and functional organization of the meiotic chromosomes. Using numerical analysis, we have investigated the relationship between the RS and the distribution of meiotic recombination events in mouse chromosome 1. Using in situ hybridization on spread mouse spermatocytes, we have examined the arrangement of different types of RSs relative to SCs. Hybridization signals of B1(Alu), B2, and minisatellite probes were localized predominantly in SCs regions. Based on the results, we proposed a model of meiotic chromosome organization. According to the model, RSs participate in the attachment of chromatin loops to SCs. |

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.
