The first production of recombinant DNA molecules, using restriction enzymes, occurred in the early s.

Recombinant DNA changes the natural genetic makeup and the characteristics of an organism by inserting DNA from another organism. Also known as genetic engineering, recombinant DNA technology is widely used in agriculture to create genetically-modified organisms that produce genetically-modified crops.

It is generated by transferring selected pieces of DNA from one organism to another. The vial shown in the photograph contains human insulin, one of the first therapeutic proteins that was genetically cloned. The drug is used to treat diabetes. Credit: Wellcome Library, London. Genetic engineering is used for many different purposes in research, medicine, agriculture and industry.

Application of recombinant DNA technology to the production of useful biomaterials

Bioproducts pp Cite as. It is now possible to clone and express a gene of interest in widely differing hosts. Among many the steps necessary for the production of useful biomaterials in industry, gene cloning, scale-up of the process, and isolation and purification of products are the most important. For the efficient cloning of specific genes, suitable host-vector systems should be selected. For the successful cultivation of recombinant organisms in a large fermentor, both expression of cloned genes and stability of recombinant plasmid are essential. For the isolation of products, protein secretion systems must be improved.

Mark A. Essays Biochem 16 October ; 63 4 : — DNA present in all our cells acts as a template by which cells are built. The human genome project, reading the code of the DNA within our cells, completed in , is undoubtedly one of the great achievements of modern bioscience. Our ability to achieve this and to further understand and manipulate DNA has been tightly linked to our understanding of the bacterial and viral world.

Recombinant DNA

Recombinant DNA rDNA molecules are DNA molecules formed by laboratory methods of genetic recombination such as molecular cloning that bring together genetic material from multiple sources, creating sequences that would not otherwise be found in the genome. Recombinant DNA is the general name for a piece of DNA that has been created by combining at least two fragments from two different sources. Recombinant DNA is possible because DNA molecules from all organisms share the same chemical structure, and differ only in the nucleotide sequence within that identical overall structure. Recombinant DNA molecules are sometimes called chimeric DNA , because they can be made of material from two different species, like the mythical chimera. R-DNA technology uses palindromic sequences and leads to the production of sticky and blunt ends.

Authors : Alemayehu Choramo and Motuma Debelo. Abstract: Human beings want enjoying highest attainable standard of basic health without discrimination of race, religion and political belief, economic or social condition. The benefits of medical, psychological and related knowledge have to be extended all people to the fullest attainment of health. Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity. Three factors affect human life greatly by: deficiency of food, health problems and environmental issues.

Recombinant DNA

Я просто попал на все готовое. Поверь. Поэтому я и узнал о его намерении модифицировать Цифровую крепость. Я читал все его мозговые штурмы. Мозговые штурмы. Сьюзан замолчала. По-видимому, Стратмор проверял свой план с помощью программы Мозговой штурм.

Ведь если кто и может справиться с возникшей опасностью, да еще без посторонней помощи, так это Тревор Стратмор. Он обладал сверхъестественной способностью одерживать верх над всеми, кто бросал ему вызов. Шесть месяцев назад, когда Фонд электронных границ обнародовал информацию о том, что подводная лодка АНБ прослушивает подводные телефонные кабели, Стратмор организовал утечку информации о том, что эта подводная лодка на самом деле занимается незаконным сбросом токсичных отходов. ФЭГ и экологи так и не смогли установить, какая из двух версий соответствует истине, и средства массовой информации в конце концов устали от всей этой истории и перешли к другим темам. Каждый шаг Стратмора был рассчитан самым тщательным образом. Строя свои планы, Стратмор целиком полагался на собственный компьютер.

 А-га. - Не хочешь составить мне компанию. У меня на столе пирог с сыром. - Хотела бы, Джабба, но я должна следить за своей талией. - Ну да? - Он хмыкнул.  - Давай я тебе помогу.

Сотни людей стояли на коленях перед алтарем, принимая причастие. Может быть, Беккер был среди. Халохот внимательно оглядывал согнутые спины.
