| Abstract | A panel of 28 mouse-human somatic cell hybrids of known karyotype was screened for the presence of the human carbonic anhydrase II (CA II) gene, which encodes one of the three well-characterized, genetically distinct carbonic anhydrase isozymes (carbonate dehydratase; carbonate hydro-lyase, EC 4.2.1.1). The human and mouse CA II genes can be clearly distinguished by Southern blot analysis of BamHI-digested genomic DNA with a mouse CA II cDNA hybridization probe. The two major hybridizing fragments in mouse were 15 and 6.0 kilobase pairs, and in human they were 15 and 4.3 kilobase pairs. Analysis of the somatic cell hybrids by this technique identified those containing human CA II gene sequences. Segregation analysis of the molecular marker and chromosomes in cell hybrids indicated a clear correlation between the presence of chromosome 8 and the human CA II gene (CA2). This finding provides the second polymorphic marker for human chromosome 8 and, moreover, a molecular disease marker, because human CA II deficiency has recently been linked to an autosomal recessive syndrome of osteopetrosis with renal tubular acidosis and cerebral calcification. |

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.
