| Abstract | This work has proposed a new theoretical approach to analysis of histograms of DNA content, which are obtained by the method of flow cytometry, in cells of Drosophila melanogaster imaginal discs. The precision of measurements of the DNA amount in G$_{1}$ and G$_{2}$(M) phases has been shown to be limited by precision of instrument tuning of zero of the flow cytometer. Use of the calculative zero of the flow cytometer and of dividing cells as standards of the DNA content is able to increase severalfold the precision of the DNA measurements in nuclei of the species. Comparative analysis of errors of various methods of measurement of the DNA content in cell nuclei is also performed. For methods of flow fluorescent cytometry, confocal scanning, and cytophotometry of the Feulgen-stained nuclei, it has been shown that, at present, the mean square errors of the DNA content measurements are within the interval of values considered acceptable for biological studies (0.02 < CV < 0.06). |

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.
