Abstract | We have examined the ability of single-stranded DNA to participate in homologous recombination reactions in mammalian cells and nuclear extracts derived from them. We have inserted a fragment of the neo gene into the single-stranded DNA phage vector M13 mp11. The neo fragment was derived from a deletion derivative of the prokaryotic-eukaryotic shuttle vector pSV2neo. The resulting single-stranded DNA was mixed with a double-stranded deletion derivative of pSV2neo and tested for recombination in human cells, monkey cells, and nuclear extracts obtained from human cells. We were able to obtain recombinant molecules containing wild-type neo genes in all three systems. Examination of the products of recombination indicated that they resulted from correction of the deletion in the double-stranded DNA substrate. We were unable to detect any extensive conversion of single-stranded DNA into its double-stranded counterpart before it participated in the recombination reaction. We have also tested the ability of single-stranded DNA to yield transfectants. When a single-stranded DNA derivative of the herpes simplex virus thymidine kinase (TK) gene was introduced into mouse L-M(TK-) cells, we were able to obtain TK+ colonies. From these results, we conclude that single-stranded DNA can participate in transfection as well as homologous recombination reactions in mammalian cells. |

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.
