| Abstract | We have demonstrated that restriction fragment length polymorphisms (RFLPs) produced by BamHI can be used as markers for constant (C) region heavy chain genes C psi gamma (C gamma pseudogene), C gamma 2, and C gamma 4. These RFLPs were found nonrandomly associated in the population sample studied. Of the eight combinations (haplotypes) of RFLPs theoretically possible, only two accounted for a total of 88% of the 116 chromosomes examined, a value greater than the total of 25% expected from random segregation of alleles. This indicates considerable linkage disequilibrium between C psi gamma, C gamma 2, and C gamma 4. Quantitative assessment of the degree of association between C gamma gene RFLPs, Gm markers, and switch region RFLPs adjacent to C mu and C alpha 1 revealed that C psi gamma is most tightly associated with C gamma 2 (r = 0.81 and 0.95 for the two common haplotypes), suggesting that C psi gamma maps to a position lying between C alpha 1 and C gamma 2. The association analysis used here should have general applicability for studying the genomic organization of other multigene families. |

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.
