| Abstract | The faithful replication of eukaryotic chromosomal DNA occurs during S phase once per cell cycle. Replication is highly regulated and is initiated at special structures, termed origins, from which replication forks move out bidirectionally. A wide variety of techniques have been developed to study the features and kinetics of replication. Many of these, such as those based on flow cytometry and two-dimensional and pulsed-field gel electrophoresis, give a population-level view of replication. However, an alternative approach, DNA fiber analysis, which was originally developed more than 50 years ago, has the advantage of revealing features of replication at the level of individual DNA fibers. Initially based on autoradiography, this technique has been superseded by immunofluorescence-based detection of incorporated halogenated thymidine analogs. Furthermore, derivations of this technique have been developed to distribute and stretch the labeled DNA fibers uniformly on optically clear surfaces. As described here, one such technique-DNA combing, in which DNA is combed onto silanized coverslips-has been used successfully to monitor replication fork progression and origin usage in budding yeast. |

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.
