Concepts of Biotechnology 2.
Biotechnology is a broad area of biology , involving the use of living systems and organisms to develop or make products. Depending on the tools and applications, it often overlaps with related scientific fields. In the late 20th and early 21st centuries, biotechnology has expanded to include new and diverse sciences , such as genomics , recombinant gene techniques, applied immunology , and development of pharmaceutical therapies and diagnostic tests.

The goal is to make products, to improve animals and to develop microorganisms for specific agricultural uses. Examples of animal biotechnology include creating transgenic animals animals with one or more genes introduced by human intervention , using gene knock out technology to make animals with a specific inactivated gene and producing nearly identical animals by somatic cell nuclear transfer or cloning. The animal biotechnology in use today is built on a long history. Some of the first biotechnology in use includes traditional breeding techniques that date back to B.
Animal agriculture is being transformed by rapid advances in biotechnology—a term that encompasses a variety of technologies, including genetic engineering GE , genetic modification, transgenics, recombinant DNA techniques, and cloning, among others. Producers are interested in the application of biotechnology to improve productivity, consistency, and quality; to introduce new food, fiber, and medical products; and to protect the environment. Potential human health applications of transgenic animals include producing biopharmaceuticals and generating organs, tissues, and cells for xenotransplantation. Criticisms of such applications involve issues ranging from food safety and social resistance to potential negative impacts on animal welfare and on ecosystems. Questions also have arisen about the adequacy of the current regulatory structure to assess and manage any risks created by these technologies.
The applications of biotechnology includes plant tissue culture, production of transgenic in animal and plants, applications in medicine as tools and therapeutics, creation of new enzymes and their immobilization for industrial use, development of monoclonal antibodies and control of pollutions, etc. The document focuses on the development and application of modern biotechnology based on new enabling techniques of recombinant-DNA technology, often referred to as genetic engineering. The history of biotechnology begins with zymotechnology, which commenced with a focus on brewing techniques for beer. By World War I, however, zymotechnology would expand to tackle larger industrial issues, and the potential of industrial fermentation gave rise to biotechnology. The oldest biotechnological processes are found in microbial fermentations, as born out by a Babylonian tablet circa B. In about B. The Sumerians were able to brew as many as twenty types of beer in the third millennium B.

Five overarching concerns of animal biotechnology dominated discussions before the committee. The first was whether anything theoretically could go wrong with any of the technologies. For example, is it theoretically possible that a vector used for gene transfer could escape and become integrated into the DNA of another organism and thereby create a hazard?

Scope and importance in crop improvement 4.
- Подождите. Я же просил меня подбросить. ГЛАВА 59 Сьюзан протянула руку, и коммандер Стратмор помог ей подняться по лестнице в помещение шифровалки.
Ему на руку была даже конструкция башни: лестница выходила на видовую площадку с юго-западной стороны, и Халохот мог стрелять напрямую с любой точки, не оставляя Беккеру возможности оказаться у него за спиной, В довершение всего Халохот двигался от темноты к свету. Расстрельная камера, мысленно усмехнулся. Халохот оценил расстояние до входа. Семь ступеней.
Ему все время казалось, что Беккер совсем рядом, за углом. Одним глазом он следил за тенью, другим - за ступенями под ногами. Вдруг Халохоту показалось, что тень Беккера как бы споткнулась. Она совершила судорожный рывок влево и вроде бы закружилась в воздухе, а затем снова прильнула к центру лестницы.
На сей раз голос его прозвучал с несвойственным ему спокойствием: - Директор, если мы введем неверный ключ… - Верно, - прервала его Сьюзан. - Если Танкадо ничего не заподозрил, нам придется ответить на ряд вопросов.
