Maintenance of the information embedded in the genomic DNA sequence is essential for life. DNA polymerases play pivotal roles in the complex processes that maintain genetic integrity. Besides their tasks in vivo, DNA polymerases are the workhorses in numerous biotechnology applications such as the polymerase chain reaction (PCR), cDNA cloning, genome sequencing, nucleic acids-based diagnostics and in techniques to analyze ancient and otherwise damaged DNA. Moreover, some diseases are related to DNA polymerase defects, and chemotherapy through inhibition of DNA polymerases is used to fight HIV, Herpes and Hepatitis B and C infections. We have recently witnessed the discovery of an abundance of novel DNA polymerases in viruses, bacteria, archaea and eukaryotes with specialized properties whose physiological functions are only beginning to be understood. This book summarizes the current knowledge of these fascinating enzymes. It is intended for a wide audience from basic scientists, to diagnostic laboratories and to clinicians who seek a better understanding of these fascinating enzymes.

An essential resource for all scientists researching cellular responses to DNA damage. • Introduces important new material reflective of the major changes and developments that have occurred in the field over the last decade. • Discussed the field within a strong historical framework, and all aspects of biological responses to DNA damage are detailed. • Provides information on covering sources and consequences of DNA damage; correcting altered bases in DNA: DNA repair; DNA damage tolerance and mutagenesis; regulatory responses to DNA damage in eukaryotes; and disease states associated with defective biological responses to DNA damage.

This series provides, in two volumes, a complete and exhaustive review of the subject of the eukaryotic nucleus, the site of the DNA. The focus of the book is how the information in the DNA is transcribed, accessed and maintained.

The book entitled “Basic Concepts of Plant Biotechnology (with MCQs)” has been publishing when the recombinant DNA and sequencing of human and many plant genomes have been completed. This book contains almost 3000 multiple choice questions as well as fill in the blanks with answers covering all aspects of molecular biological systems of prokaryotes and eukaryotes. In writing the first edition, the aim is to provide all simple and difficult questions for weak students in plant molecular biology that have no more knowledge and have more problems in solving the questions. Therefore, in this book we included questions belongs to all basic concept of molecular biology which will provide strong knowledge to students preparing for competitive exams of life science like CSIR-NET, DBT-JRF, ICMR-JRF, ICAR-NET, ARS, PSC, graduate and post-graduate exams.

CD-ROM includes animations, living graphs, biochemistry in 3D structure tutorials.
