Bt toxin is produced by a bacterium called <em>Bacillus thuringiensis<\/em>.Bt 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. Examples are Bt cotton, Bt corn, rice, tomato, potato and soyabean etc<\/p>\n<p><strong>Bt cotton<\/strong>&#8211; Bacterium <em>Bacillus thuringiensis<\/em> produce proteins that kill certain insects like lepidopterens, colepterans (beetels) and dipterans (flies, mosquitoes).<\/p>\n<ul>\n<li><em>B. thuringiensis<\/em>produce crystals that contain a toxic <strong>insecticidal protein.<\/strong> 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.<\/li>\n<li>The gene from B. thuringiensishas been incorporated into several crop plants like cotton, maize, rice etc. The toxin is coded by a gene named <strong>cry. <\/strong>The protein coded by the genes crylAb and cryIIAb control the cotton bollworms, cryIAb controls corn\u00a0borer.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Pest_Resistant_Plants\"><\/span><strong>Pest Resistant Plants <\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li>Nematodes like <em>Meloidegyne incognitia<\/em> infects the roots of tobacco plants and causes reduction in yield.

The main source of this insulin was isolation of insulin from animals.

The main challenge for production of insulin using rDNA technique was getting insulin assembled into a mature form.<\/li>\n<li>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. Chain A and Chain B were produced separately, extracted and combined by creating disulphide bonds to form human insulin.<\/li>\n<\/ul>\n<p><img decoding=\"async\" src=\"https:\/\/media-mycbseguide.s3.amazonaws.com\/images\/static\/review\/4934_1.jpg\" alt=\"\" \/><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Gene_Therapy\"><\/span><strong>Gene Therapy<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>It is a collection of methods that allows correction of a gene defect that has been diagnosed in a child or embryo. This method is applied in a person with a hereditary disease. In this method, genes are inserted into a person\u2019s cells and tissues to treat a disease.<\/p>\n<ul>\n<li>The correction of gene defect involves delivery of a normal gene into the individual or embryo to take over the function of and compensate for non-functional gene.<\/li>\n<li>The first clinical gene therapy was done in 1990 to a 4 year old girl with adenosine deaminase (ADA) deficiency. This disorder is caused due to the deletion of the gene for adenosine deaminase that is essential for immune system to function. This defect can be treated by enzyme replacement therapy in which functional ADA is given to the patient by injection or bone marrow transplant.<\/li>\n<li>In gene therapy method lymphocytes from the blood of the patient are grown in culture medium outside the body. A functional ADA cDNA is then introduced into these lymphocystes and returned to the patient. In this method periodic infusion of such genetically engineered lymphocytes is needed. If gene isolated from bone marrow cells producing ADA is introduced into cells at early embryonic stages, it could be a permanent cure.<img loading=\"lazy\" decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/media-mycbseguide.s3.amazonaws.com\/images\/static\/review\/4934_4.jpg\" alt=\"\" width=\"209\" height=\"156\" \/><\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Molecular_Diagnosis\"><\/span><strong>Molecular Diagnosis <\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Conventional method of diagnosis such as serum or urine analysis is not able to early detection of disease causing pathogens or virus.

Enzyme Linked Immuno-sorbent Assay (ELISA).<\/p>\n<ul>\n<li>Symptoms of disease appear only when the concentration of pathogen get increased significantly. Low concentration of bacteria and virus can be detected by amplification of nucleic acid by PCR. It detects the mutation in the gene in cancer patient. PCR is routinely used to detect the HIV in suspected AIDS patients. Genetic disorder can be also detected by using PCR technique.<\/li>\n<li>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 clone having the mutated gene will not appear on the photographic film.<\/li>\n<li>ELISA is based on the principle of antigen-antibody interaction.

Common reasons for development of transgenic animals-<\/p>\n<p>a) <strong>Normal physiology and development<\/strong>&#8211; they are designed to allow the study of gene regulation, their effect on normal function of body.

Transgenic model has been developed for disease like cancer, cystic fibrosis, Alzheimer\u2019s disease etc.<\/p>\n<p>c) <strong>Biological products<\/strong>&#8211; .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 \u2013 1-antitrypsin) used to treat emphysema.\u00a0 The first transgenic cow, Rosie, produced human protein-enriched milk (alpha-lactalbumin &#8211; 2.4 gm \/ litre).<\/p>\n<p>d) <strong>Vaccine safety<\/strong>&#8211; transgenic mice are developed for used in testing the safety of vaccine before they are used on human. Polio vaccine was tested on transgenic mice and then on monkey.<\/p>\n<p>e) <strong>Chemical safety testing<\/strong>&#8211; transgenic animals are made that carry genes which make them more sensitive to toxic substances than non-transgenic animals.

Now, patents are granted for biological entities and for products derived from biological resources.<strong>Biopiracy:<\/strong><br \/>\nIt is the term used to refer to the use of bio-resources by multinational companies and other organizations without proper authorization from the countries and people concerned without compensatory payment.<\/p>\n<p>In 1997, an American company got patent rights on Basmati rice through the US Patent and Trademark Office.\u00a0 This allowed the company to sell a \u2018new variety of Basmati, in the US and abroad.\u00a0 This \u2018new\u2019 variety of Basmati had actually been derived from Indian farmer\u2019s varieties. Indian Basmati was crossed with semi-dwarf varieties and claimed as an invention or a novelty.<\/p>\n<p>Several attempts have also been made to patent uses, products and processes based on Indian traditional herbal medicines, e.g., turmeric and neem.<strong>\u00a0 \u00a0 \u00a0<\/strong><\/p>\n<h2><span class=\"ez-toc-section\" id=\"CBSE_Class_12_Revision_Notes_and_Key_Points\"><\/span><strong>CBSE Class 12 Revision Notes and Key Points<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>CBSE quick revision note for class 12 Chemistry Physics Maths, Biology and other subject are very helpful to revise the whole syllabus during exam days.
