| Abstract | The physiological importance of translational regulation in controlling the synthesis of ribosomal proteins from the L11 ribosomal protein operon was determined for the classical regulatory phenomena of growth rate dependence and stringent control. Translational regulation of the L11 operon by ribosomal protein L1, the L11 operon-specific translational repressor protein, was abolished by introducing a chromosomal mutation that causes an alteration of the site where L1 interacts with L11 operon mRNA. It was found that abolishing translational regulation of the L11 operon also abolished growth-rate-dependent regulation and stringent control of the L11 operon ribosomal proteins without affecting the normal regulation of ribosomal proteins from other operons that are not regulated by L1. These results show that both growth-rate-dependent control and stringent control of ribosomal protein synthesis in the L11 operon are a direct result of translational regulation. |

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.
