Recombinant DNA-technology is of great importance in the field medicine. With the help of a flow chart, show how this technology has been used in preparing genetically engineered human insulins .

Why is recombinant DNA (rDNA) technology called genetic engineering

Recombinant DNA technology has made possible to engineer microbes, plants and animlas such that they have novel capabilities .

Recombinant DNA technology become possible only after the discovery of enzyme restriciton endonuclesase till now how many restriction enzymes have been isolated .

(i) How and at what stage does Plasmodium enter into a human body ? (ii) With the help of a flow-chart only show the stages of asexual reproduction in the life-cycle of the parasite in the infected human. (iii) Why does the victim show symptoms of high fever ?

Find out which among the following is true and which is false (i) Recombinant DNA technology has made it possible to engineer microbes, plants and animals such that they have novel capabilities. (ii) Genetically modified organisms have been created by using methods other than natural methods to transfer one or more genes from organism to another, generally using techniques such as recombinant DNA technology. (iii) GM plants have been useful in increasing crop yields, reduce post harvest losses and make crops more tolerant of stressess. (iv) Recombinant DNA technology process have made immense impact in the area of healthcare by enabling mass production of safe and more effective therapeutics. (v) since the recombinant therapeutics are identical to human proteins, they do not induced unwanted immunological responses.

Biotechnology can be defined as the use of biological processes in industry and technology. During the past three decades biotechnology has gained attention due to the gene cloning process. Biotechnological applications are playing important role in agriculture. They are used in agro-chemical based agriculture, in organic farming, genetically engineered crop-based agriculture. The green revolution is the milestone or result of these biotechnological processes. Whihc among the following may be considered as an application of biotechnology ?

In recombinant DNA technology before the use of restriction endonuclease , we have to isolated and precipitate the genetic material (DNA) . For this purpose we use following different enzyme / chemical :

The following flow chart shows methodology which has been used for cattle, sheep, buffaloes etc. Identify missing steps (A, B and C)
