| Abstract | The synthesis of a gene coding for horseradish peroxidase (HRP, isozyme c; EC 1.11.1.7) is described using a polymerase chain reaction (PCR)-mediated gene synthesis approach developed in our laboratory. In this approach, all the oligonucleotides making up the gene are ligated in a single step by using the two outer oligonucleotides as PCR primers and the crude ligation mixture as the target. The PCR facilitates synthesis and purification of the gene simultaneously. The gene for HRP was synthesized by ligating all 40 oligonucleotides in a single step followed by PCR amplification. The gene was also synthesized from its fragments by using an overlap extension method similar to the procedure as described [Horton, R. M., Hunt, H. D., Ho, S. N., Pullen, J. K. & Pease, L. R. (1989) Gene 77, 61-68]. A method for combining different DNA fragments, in-frame, by using the PCR was also developed and used to synthesize the HRP gene from its gene fragments. This method is applicable to the synthesis of even larger genes and to combine any DNA fragments in-frame. After the synthesis, preliminary characterization of the HRP gene was also carried out by the PCR to confirm the arrangement of oligonucleotides in the gene. This was done by carrying out the PCR with several sets of primers along the gene and comparing the product sizes with the expected sizes. The gene and the fragments generated by PCR were cloned in Escherichia coli and the sequence was confirmed by manual and automated DNA sequencing. |

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.
