answr. -  Insulin from It also prevents a number of diseases. This helps in formation of genetically modified insulin known as humulin. (pro-insulin). Genetically modified crops have their genes altered by inserting the genes with desired characteristics. This biotechnology application is very important in healthcare because it allows for the mass production of safe and more effective medicines. interaction.

Some protein coding genes isolated from pathogens are also incorporated and expressed in plants produce antigens and are also called edible vaccines. The clone having mutated gene will not appear on the photographic film, because the probe will not have complementarity with the mutated gene. American company) prepared two DNA sequences corresponding to A & B chains PCR. Biotechnological Applications in Agriculture and Medicine: 1. Biotechnology and Its Applications. Of these, 12 are being marketed in India. Ans: Bacteria having gene or genes usually from an unrelated organism incorporated into their genome are called transgenic bacteria. Animal Kingdom - Notes | Class 11 | Part 2: Porifera. (f) Specific Bt toxin genes were isolated from Bacillus thuringiensis and incorporated into several crop plants as cotton. -  It is a method to correct a gene by detecting the antibodies synthesized against the pathogen. This caused allergy or other reactions in some patients. To detect gene mutations in (f) Tailor made plants are created by using GM plants to supply alternative resources to industries, in the form of starches, fuels and pharmaceuticals. (v) Some of the applications of biotechnology in agriculture are the production of pest resistant plants, which decrease the amount of pesticide used. such problems. Genetically engineered crop-based agriculture. (b) Insulin consists of two short polypeptide chains, i.e. It involves silencing of a specific mRNA due to a complementary dsRNA. -  Insulin is used to manage (a) Protein vaccines use of specific protein produced by rDNA in vaccine. Applications of Biotechnology in Medicine. -  Infection by pathogen can be • Let us have a look at some of the important applications of Biotechnology. Biotechnology and its Applications class 12 Notes Biology.

Explain with examples. person’s cells and tissues to treat a hereditary disease. • Enzyme Linked Immuno Sorbent Assay (ELISA) is based on the principle of antigen-antibody interaction. The drugs are mainly produced by the process of genetic engineering. • - However, very low concentration of a bacteria or virus can be detected by amplification of their nucleic acid by 10. Hepatitis vaccine contains the viral envelope protein, hepatitis-B surface antigen (HB8 Ag). The recombinant DNA technology has added to the advancements in the field of healthcare by permitting mass production of safe and more effective therapeutic drugs. To study how genes are regulated and how do they affect the normal functioning of the body and its development. enzyme replacement therapy (injection of ADA). 2. You may have already learnt about Recombinant DNA (rDNA) technology. the non-functional gene. ELISA is performed based on the principle of antigen-antibody interaction, infection by pathogen can be detected by the presence of antigens or by detecting the antibodies synthesized against the pathogen. Illustrate using any one example. It is done in the following steps: therapeutics have been approved. -  Molecular diagnosis helps to solve the problem of early diagnosis and treatment of diseases. It was developed at Swiss Federal Institute of Technology by Professor Ingo Potrykus and Peter Beyer. (d) The source of this complementary RNA could be from an infection by viruses having RNA genomes or mobile genetic elements (transposons) that replicate via an RNA intermediate. • A functional ADA cDNA (using a retroviral vector) is then introduced into these lymphocytes, which are subsequently returned to the patient. (a) Improved crop varieties.
