NEET Biotechnology & It's Application Important Questions

Name the technique based on the principle of antigen-antibody interaction used in detection of a virus HIV. Development of a transgenic food crop may help in solving the problem of night blindness in the developing countries, name this crop plant. Golden Rice. Which nematode infects the roots of tobacco plant and causes a great reduction in yield? The first transgenic cow, produced human protein — enriched milk.

Name the cow and the protein found in milk. Rosie, alpha-lactalbumin. The insulin produced using recombinant DNA technology is more advantageous than the insulin extracted from pancreas of slaughtered cattle and pigs. Insulin obtained from animal source causes allergy. Name two pest resistant plants produced by using recombinant DNA technology. Name the genetically engineered human Insulin? Write the Scientific name of nematode that attacks the root of tobacco plant?

Define a patent? Expand GEAC. Genetic Engineering Approval Committee. Which vaccine was being tested on mice? Polio vaccine. Name the bacterium which is used to produce insect-resistant plants by genetic engineering. Bacillus thuringiensis. Name any disease against which vaccine is developed lay Recombinant DNA technology. Hepatitis B vaccine. PCR polymerase chain reaction. Name any two diseases for which transgenic mice are used as model organisms.

Cry is the gene which codes for Bt-toxin which is an insecticidal protein while CRY is the protein coded by cry genes. Name any one disease for which gene therapy has been proved effective?

Adenosine deaminase deficiency ADA. What are the two methods for correcting ADA deficiency in a child? Bone marrow transplantation having functional ADA enzyme and Enzyme replacement therapy.

Some crop plants are modified genetically by manipulating their genes. How are they made beneficial? More tolerant to abiotic stresses; pest resistant; reduction in post harvest losses; increased nutritional value of food.

Write its full form. Give its two objectives. Justify the statement with a suitable example. Industrialised nations are collecting and patenting the genetic resources of under industrialised country like India. An American Company got patent rights on Basmati rice. Valuable biomolecules obtained from bioresources are patented and used for commercial purposes. What is Golden rice? What is its advantage? Golden rice is a transgenic variety of rice which contains a gene which codes for Vitamin A precursor.

What are the three critical research areas in the field of Biotechnology? What are the advantages of molecular diagnostics over conventional methods? In conventional methods, presence of pathogen is normally suspected only when pathogen has produced a disease symptom.

By this time the concentration of pathogen is already very high in Body which could be harmful but with molecular diagnostics, Small amount of pathogen could be detected by amplification by PCR.

What are genetically modified organisms? Name two factors on which their behaviour depends? Those organisms whose genes have been altered by manipulation, are called genetically modified organism or transgenic organisms.

The two factors on which their behaviourdepends:- i proper insertion of gene of interest. What are transgenic Bacteria? Illustrate using any one example? The bacteria in which genes of interest i-e. Give any two examples of products, how transgenic animals can be used to produce biological compounds? How is autoradiography used to detect a mutated gene? A single stranded DNA or RNA tagged with radioactive molecule is allowed to hybridise to its complements DNA in a clone of cells followed by detection using autoradiography.

The clone having the mutated gene will hence not appear on photographic film because probe will not have complementarily with mutated gene. Whydid Bacterial toxin does not kill the bacteria but only the insects? Bacterial toxin does not kill the Bacillus because. But toxic protein exist as inactiv e protoxin but once an insect ingest the inactive protoxin it is converted into active form of toxin due to alkaline pH of gut which solublises the crystal. Mention any four applications of Biotechnology in the field of Agriculture?

Vit — A rich golden rice. Why is recombinant Insulin produced by genetic engineering need to be processed? Some multinational companies and other organisations are using bioresources for commercial benefits, without proper authentication and compensation to concerned authorities.

Toxins bind to surface of midgut and cause perforation, swelling, lysis of cells ultimately leading to death. Given below is an incomplete flow chart showing the process of production of nematode resistant tobacco plants based on RNAitechnique. Describe with example, Why transgenic animals are produced? Transgenic animals are produced for following purposes Describe how nematode — resistant transgenic plants have been obtained?

The specific genes fromparasite are introduced into plant using Agrobacterium. What are Cry proteins? Name an organism that produces it.

How has man exploited this protein to his benefit? Write an account on the production of human insulin in transgenic organisms. The prohormone contains another polypeptides called C-peptide which is removed during maturation. What is RNA Silencing? How is this strategy used to create pest — resistant plants? This strategy is used toprevent infection of roots of tobacco plants lay nematode Meloidegyne incognita.

Using Agrobacterium vector nematode specificgenes were introduced into host plant. The consequence wasthat parasite could not survive in transgenic host. What are the steps involved in synthesis of genetically engineered insulin. Steps involved in Insulin production are The clinical gene therapy is given to a 4 years old patient for an enzyme which is crucial for the immune system to function.

Observe the therapeutical flow chart and give the answer of the following: a Complete the missing steps B and D b Identify the disease to be cured. Step D : Infusion of genetically engineered lymphocytes into patients. In the given figure, Agrobacterium is utilized for the production of a transgenic crop. Explain the steps a, b, c, d and e shown in the figure. Step a Plasmid is removed and cut open with restriction endonuclease.

Step b Gene of interest is isolated from another organism and amplified using PCR Step c New gene is inserted into plasmid Step d Plasmid is put back into Agrobacterium Step e Agrobacterium based transformation. In the given figure, Form A and Form B represents different forms of a proteinaceous hormone secreted by pancreas in mammals.

How these forms differ from each other? Chains A and B were producedseparately, extracted and combined by creating disulphide bonds to form insulin.

What is Gene therapy — Illustrate using example of Adenosine deaminase deficiency? Gene therapy is a collection of methods that allows correction of a gene defect. Itinvolves delivery of a normal gene into the individual or embryo to replace the defective mutant allele of the gene. These lymphocytes are then transferred into body of patient the patient requires infusion of such genetically engineered lymphocytes. Your email address will not be published.
