Techniques In Genetic Engineering

Although designed for undergraduates with an interest in molecular biology, biotechnology, and bioengineering, this book—Techniques in Genetic Engineering—IS NOT: a laboratory manual; nor is it a textbook on molecular biology or biochemistry. There is some basic information in the appendices about core concepts such as DNA, RNA, protein, genes, and genomes; however, in general it is assumed that the reader has a background on these key issues. Techniques in Genetic Engineering briefly introduces some common genetic engineering techniques and focuses on how to approach different real-life problems using a combination of these key issues. Although not an exhaustive review of these techniques, basic information includes core concepts such as DNA, RNA, protein, genes, and genomes. It is assumed that the reader has background on these key issues. The book provides sufficient background and future perspectives for the readers to develop their own experimental strategies and innovations. This easy-to-follow book presents not only the theoretical background of molecular techniques, but also provides case study examples, with some sample solutions. The book covers basic molecular cloning procedures; genetic modification of cells, including stem cells; as well as multicellular organisms, using problem-based case study examples.

Assists policymakers in evaluating the appropriate scientific methods for detecting unintended changes in food and assessing the potential for adverse health effects from genetically modified products. In this book, the committee recommended that greater scrutiny should be given to foods containing new compounds or unusual amounts of naturally occurring substances, regardless of the method used to create them. The book offers a framework to guide federal agencies in selecting the route of safety assessment. It identifies and recommends several pre- and post-market approaches to guide the assessment of unintended compositional changes that could result from genetically modified foods and research avenues to fill the knowledge gaps.

Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.

Authored by an integrated committee of plant and animal scientists, this review of newer molecular genetic techniques and traditional research methods is presented as a compilation of high-reward opportunities for agricultural research. Directed to the Agricultural Research Service and the agricultural research community at large, the volume discusses biosciences research in genetic engineering, animal science, plant science, and plant diseases and insect pests. An optimal climate for productive research is discussed.

Genetic manipulation is no longer the province of the specialized researcher. It is finding widespread application in all fields of medicine and biology. Nevertheless, application of these relatively new techniques to new areas of research is often fraught with unexpected problems and difficulties. Based on the Society for Applied Bacteriology's Autumn 1989 Conference, this unique volume covers a wide and very up-to-date range of techniques used in genetic engineering. These include the isolation and analysis of DNA and RNA from cells and tissues, the selection and use of phage and plasmic vectors for cloning DNA, the cloning procedures, the production and screening of genomic libraries, the production and use of DNA probes, the polymerase chain reaction and the synthesis of 'designer' genes. This volume contains many examples of the applications of the above and other techniques for genetic manipulation, to subjects as diverse as plant pathology, forensic science, bacterial taxonomy, cardiac research, diagnostic microbiology, food hygiene and sewage treatment.

"The book...is, in fact, a short text on the many practical problems...associated with translating the explosion in basic biotechnological research into the next Green Revolution," explains Economic Botany. The book is "a concise and accurate narrative, that also manages to be interesting and personal...a splendid little book." Biotechnology states, "Because of the clarity with which it is written, this thin volume makes a major contribution to improving public understanding of genetic engineering's potential for enlarging the world's food supply...and can be profitably read by practically anyone interested in application of molecular biology to improvement of productivity in agriculture."

Genetics and Genetic Engineering explores the great discoveries in genetics-the study of genes and the inherited information they contain. Genetic engineering alters the genetic make-up of an organism using techniques that remove heritable material or that introduce DNA prepared outside the organism either directly into the host or into a cell that is then fused or hybridized with the host. This involves using recombinant nucleic acid (DNA or RNA) techniques to form new combinations of heritable genetic material followed by the incorporation of that material either indirectly through a vector system or directly through micro-injection, macro-injection and micro-encapsulation techniques. Genetic engineering, also called genetic modification, is the direct manipulation of an organism's genes using biotechnology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms. New DNA is obtained by either isolating or copying the genetic material of interest using recombinant DNA methods or by artificially synthesizing the DNA. A construct is usually created and used to insert this DNA into the host organism. The first recombinent DNA molecule was made by Paul Berg in 1972 by combining DNA from the monkey virus SV40with the lambda virus. As well as inserting genes, the process can be used to remove, or "e;knock out"e;, genes. The new DNA can be inserted randomly, or targeted to a specific part of the genome. This book will prove equally useful for physicians, nurses, animal breeders, and laboratory technicians-in fact, everyone whose daily work involves genetics and genetic engineering.

Potential benefits from the use of genetically modified organismsâ€"such as bacteria that biodegrade environmental pollutantsâ€"are enormous. To minimize the risks of releasing such organisms into the environment, regulators are working to develop rational safeguards. This volume provides a comprehensive examination of the issues surrounding testing these organisms in the laboratory or the field and a practical framework for making decisions about organism release. Beginning with a discussion of classical versus molecular techniques for genetic alteration, the volume is divided into major sections for plants and microorganisms and covers the characteristics of altered organisms, past experience with releases, and such specific issues as whether plant introductions could promote weediness. The executive summary presents major conclusions and outlines the recommended decision-making framework.
