| Abstract | Since the development of light-responsive amino acids, the activity of numerous biomolecules has been photomodulated in biochemical, biophysical, and cellular assays. Biological problems of even greater complexity motivate the development of quantitative methods for controlling gene activity with high spatial and temporal resolution, using light as an external trigger. Photoresponsive DNA and RNA oligonucleotides would optimally serve this purpose, but have proven difficult to expand from proofs-of-concept to in vivo experiments. Until recently, the development of this technology was limited by the synthesis of oligonucleotides whose function could be significantly modulated with near-UV light. New synthetic protocols and strategies for both up- and down-regulating gene activity finally make it possible to address biological considerations. In the near future, we can expect photoresponsive DNA and RNA molecules that are relatively non-toxic, nuclease-resistant, and maintain their specificity and activity in vivo. Quantitative, laser-initiated methods for controlling DNA and RNA function will illuminate new areas in cell and developmental biology. |

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.
