It is required for the proper functioning of immune system. is Agrobacterium. 19. The advantage of these techniques is that they help in early detection and treatment of diseases, which is not possible by the conventional diagnostics. 35. (ii) A functional ADA, cDNA (using a Retro viral vector) is then introduced into these lymphocytes. Ans. (i) DNA sequences corresponding to the two polypeptide, A and B-chains of insulin are synthesised in vitro. (i) Btcotton plants are genetically modified plants that contain crygene obtained from Bacillus thuringiensis (Bt). (iii) This bacterium is cloned under suitable conditions. Role of systematic in applied biology (agriculture, forestry, public health and wildlife management. (i) DNA sequences corresponding to the two polypeptide, A and B-chains of insulin are synthesised in vitro. [All India 2014C] (iv) The transgene is expressed in the form of polypeptides A and B, secreted into the medium. Thus, the main challenge for the production of insulin using rDNA techniques was getting insulin assembled into a mature form. List two ways by which an infection can be detected by this test. Molecular diagnostic techniques to pathogens are as follow: Bt toxin protein exist as inactive protoxins, but once an insect ingests the inactive toxin, it is converted into an active form of toxin due to the alkaline pH of the gut, which solublise the crystals. Chains-A and B were produced separately, extracted and combined by creating disulphide bonds to form human insulin. Tailor made plants are created by using GM plants to supply alternative resources to industries, in the form of starches, fuels and pharmaceuticals. And it will be use full in my medical field. It is concerned with everything involving a life form—no matter how small or large—including its structure, behavior, origin, growth, and reproduction. Biochemistry is a valuable subject in medicine … dsRNA binds and prevents translation of the mRNA (silencing). [Delhi 2010; All India 2008] How has biotechnology helped in producing Meloidogyne incognita resistant tobacco plant? (b) The transgenic plants, i.e. [Delhi 2013c] It is caused due to the deletion of gene for adenosine deaminase. 51. (i) When Meloidogyne incognita (parasite) consumes cells with RNAi gene, parasite cannot survive and this prevents infection. This enzyme is crucial for immune system functioning in humans. Thanks! Ans. (i) Plasmid is an extra chromosomal, self-replicating, circular, double stranded DNA molecule found naturally in bacteria.
Textbook content produced by OpenStax is licensed under a (i) DNA ligase enzyme is used to join two DNA fragments from their ends. These are of two types: (iii) This bacterium is cloned under suitable conditions. An overview of interactions among tick species, tick-borne microorganisms and hosts is provided.
(c) In mammals, insulin is synthesised as a prohormone (needs to be processed before it becomes a fully mature and functional hormone) which contains an extra stretch called the C-peptide. [Foreign 2011] [Delhi 2014C] [All India 2013] (credit: Ingrid Moen et al. Although several recombinant proteins used in medicine are successfully produced in bacteria, some proteins need a eukaryotic animal host for proper processing. The clone having mutated gene will not appear on the photographic film, because the probe will not have complementarity with the mutated gene.
In nature, the disease-causing A. tumefaciens have a set of plasmids that contain genes that integrate into the infected plant cellâs genome. For centuries man relies on animals for travel. (i) ADA is caused due to deletion of gene for adenosine deaminase. A nematode Meloidogyne incognita infects the roots of tobacco plants, which reduces the production of tobacco. Role of Molecular Biology in Cancer Treatment: A Review Article. Ans.
In some cases in which a genetic disease is present in an individualâs family, family members may be advised to undergo genetic testing. It is used in clinical diagnosis, manufacture of various biological products, treatment of diseases, nutrition, agriculture, etc. These proteins when expressed in cotton crops through genetic engineering confers pest resistance against cotton bollworms and prevents damage. vitamin-A enriched rice. role of plant physiology in agriculture Write the cause of the disease and the effect it has on the patient. I’m in a situation where I find myself struggling to choose a topic for thesis that would align biochemistry to nursing. It is extremely important to know the correct category names of such pests before their proper control. Asked by Wiki User. 13. Bttoxin is coded by crygene and produced by bacterium Bacillus thuringiensis (Bt). I so much love this article and I must say a big thank you…please can u send similar articles to my email, I’m a biochemistry student so I’ll love to get more of this, Its really good article about the importance of biochemistry and a biochemist. There are a number of various types of diseases which are spread by many type arthropod insects which are disease specific.
