| Abstract | The bacteriophage T4 unf gene, known to be involved in the arrest of transcription from cytosine-containing DNA, is unessential except in Escherichia coli strains containing plasmid pR386. Comparative genetic and biochemical analyses of parameters of unf+ and unf- phage growth in host cells isogenic except for the presence or absence of plasmid pR386 have shown that unf gene function is required for late phage DNA synthesis in the presence of the plasmid. Shutoff of host DNA, RNA, and protein syntheses, degradation of host DNA, adsorption, injection, and early phage DNA, RNA, and protein syntheses all occurred with normal or near-normal kinetics in unf- infections, even in the presence of the plasmid. The switch from early to late protein synthesis occurred in plasmid pR386-containing cells infected with unf+ or unf- phage. However, this switchover was slow in both cases and may be slower in unf- infections than in unf+ infections. Net incorporation of [3H]thymidine terminated at about 30 min after infection of pR386-containing cells with unf- phage at 30 degrees C. Alkaline sucrose gradient studies of the intracellular pools of replicative DNA in unf-infected plasmid pR386-containing cells indicated that this DNA is not detectably nickel or cleaved at the time that DNA synthesis aborts. The addition of chloramphenicol subsequent to early enzyme synthesis prevented the arrest of DNA synthesis in plasmid-containing cells infected with unf-phage. |

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.
