| Abstract | Maternal inheritance determine the charge on the large subunit of fraction I protein whereas both parents of an interspecific F(1) hybrid plant make an equal contribution to the charge of the small subunit. Experiments were performed to test whether fraction I protein in the hybrid plant was a hybrid molecule or two kinds of protein molecules, one composed of large subunits combined with small subunits of the male type and the other composed of large subunits combined with small subunits of the female type. A mixture of fraction I proteins from Nicotiana langsdorffii and N. bonariensis was resolved into two components of different charge by agarose gel electrophoresis but the protein from the F(1) hybrid plant between the two species was a single component. However, two-dimensional agarose gel electrophoresis showed that fraction I protein from an F(1) hybrid could be highly heterogeneous in charge compared to a fraction I protein containing a single small subunit polypeptide that was homogeneous in charge. Evidently, charge heterogeneity results from random self-assembly of the small subunit polypeptides. Random self-assembly of small subunits of two types could result in a mixture in which 99.2% of the population are hybrid molecules composed of seven types together with 0.39% containing small subunits of the maternal type and 0.39% containing those of the paternal type. In an F(1) hybrid plant in which three small subunit polypeptides randomize during assembly, a mixture of 45 types of fraction I protein macromolecules could be present. |

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.
