BIOTECHNOLOGY AND ITS APPLICATIONS CLASS 12 NOTES PDF DOWNLOAD . The first transgenic cow, Rosie, produced human protein-enriched milk (alpha-lactalbumin - 2.4 gm / litre). Several attempts have also been made to patent uses, products and processes based on Indian traditional herbal medicines, e.g., turmeric and neem.

Study of disease- a number of transgenic animals are designed to increase our understanding of how genes contribute to the development of disease. Download Free Lecture Notes-Pdf Link-XVII Downstream processing technologies to purify the protein or organic compounds. ), which will make decisions regarding the validity of GM research and the safety of introducing GM-organisms for public services. The Indian Government has set up organizations such as, GEAC (Genetic Engineering Approval Committee. Plants, bacteria, fungi and animals whose genes have been altered by manipulation are called Genetically Modified Organisms (GMO). Transgenic mice, rats, rabbits, pigs, sheep, cows and fish have been produced. In humans, insulin is synthesised as a prohormone, which contains an extra stretch called C peptide, which is absent in mature insulin. Chemical safety testing- transgenic animals are made that carry genes which make them more sensitive to toxic substances than non-transgenic animals. The gene from B. thuringiensishas been incorporated into several crop plants like cotton, maize, rice etc. Examples are Bt cotton, Bt corn, rice, tomato, potato and soyabean etc. Adult -onset diabetes can be controlled by taking insulin at regular intervals. In gene therapy method lymphocytes from the blood of the patient are grown in culture medium outside the body. Enhanced nutritional value of food, eg., Vitamin ‘A’ enriched rice. This method is applied in a person with a hereditary disease. Enter your email address to subscribe to this blog and receive notifications of new posts by email. Industrial biotechnology: Tools and applications Because of its association with reduced energy consumption,, This paper reviews several key issues surrounding modern gene technology and its application in applications in agriculture, Key Issues in Biotechnology … Polio vaccine was tested on transgenic mice and then on monkey. Low concentration of bacteria and virus can be detected by. By introducing genes from other species that alter the formation of this factor and studying eh biological affects that results. Nematodes like Meloidegyne incognitia​​ infects the roots of tobacco plants and causes reduction in yield. A single stranded DNA or RNA having radioactive molecule is allowed to hybridise to its complementary DNA in a clone of cells followed by detection using autoradiography. The toxin is coded by a gene named, The protein coded by the genes crylAb and cryIIAb control the cotton bollworms, crylAb controls, ​​ infects the roots of tobacco plants and causes reduction in yield. Indian Basmati was crossed with semi-dwarf varieties and claimed as an invention or a novelty. At present, about 30 recombinant therapeutics have been approved for human use the world over. It can be used in agro-chemicals, organic agriculture, and genetically . Nematode specific genes were introduced into host plant using Agrobacterium vectors. The protein coded by the genes crylAb and cryIIAb control the cotton bollworms, crylAb controls. In this method periodic infusion of such genetically engineered lymphocytes is needed. The infestation of these nematodes can be prevented by the process of RNA interference (RNAi). - .Transgenic animals that produce useful biological products can be created by the introduction of the portion of DNA (gene) which codes for a particular product such as human protein (alpha - 1-antitrypsin) used to treat emphysema. The main source of this insulin was isolation of insulin from animals. RNAi is present in all eukaryotic organisms as cellular defence by silencing of specific mRNA due to complementary dsRNA molecules that bind to and prevents translation of the mRNA. Class 12 Biology Notes Chapter 12 Biotechnology And Its Application. GM plants have many applications-, Made crops more tolerant to abiotic stresses, Increased efficiency of mineral usage by plants. Infection by pathogen can be detected by the presence of antigens like proteins, glycoproteins etc. Insulin was earlier extracted from pancreas of slaughtered cattle and pigs but insulin from these sources develops allergy or other types of reactions to the foreign protein. If gene isolated from bone marrow cells producing ADA is introduced into cells at early embryonic stages, it could be a permanent cure. Biological products- .Transgenic animals that produce useful biological products can be created by the introduction of the portion of DNA (gene) which codes for a particular product such as human protein (alpha - 1-antitrypsin) used to treat emphysema. This defect can be treated by enzyme replacement therapy in which functional ADA is given to the patient by injection or bone marrow transplant. B. thuringiensisproduce​​ crystals that contain a toxic insecticidal protein. Contrary to its name, biotechnology is not a single … Bt toxin is produced by a bacterium called, ​​ toxin gene has been cloned from the bacteria and been expressed in plants to provide resistance to insects without the need for insecticides; in effect created a bio-pesticide. This toxic protein present in bacterium as inactive protoxins but as soon as insect ingest the inactive form due to alkaline pH of gut, it converted into an active form of toxin and bind to surface of midgut epithelial cells and create pores that cause cell swelling and lysis and eventually death of insect. PCR is routinely used to detect the HIV in suspected AIDS patients. ​​ produce proteins that kill certain insects like lepidopterens, colepterans (beetels) and dipterans (flies, mosquitoes). Genetically modified . An American company, Eli Lilly in 1983 prepared two DNA sequence corresponding to A and B chain of human insulin and introduced them in plasmids of E.coli to produce insulin chain. In India, 12 of these are presently being marketed. Biotechnological Applications in Agriculture- food production can be increased by. This is possible only when you have the best CBSE Class 12 Biology Notes, study material, and a smart preparation plan. BIOTECHNOLOGY AND ITS APPLICATIONS. - transgenic mice are developed for used in testing the safety of vaccine before they are used on human. engineered crop-based agriculture. PDF download free. Insulin consists of two short polypeptide chains- chain A and chain B, that are linked together by disulphide bridges.
