  • Question 1
    1 / -0

    Biopiracy of Indian plant by USA is

    Solution
    The exploitation of biological resources or the use of biological resources without permission is called as biopiracy. Mustard is an indigenous crop of India, jasmine rice is the of Thailand and Melon fruit seed is of south Asia but now US companies are claiming ownership on them. Thus, the correct answer is option A.
  • Question 2
    1 / -0

    The method of biopiracy is _________.

    Solution
    Biopiracy is the term used to refer to the use of bio-resources by multinational companies and other organisations without proper authorisation from the countries and people concerned without compensatory payment. Thus option A is the correct answer.

  • Question 3
    1 / -0
    The injecting of foreign gene in an animal gives rise to 
    Solution
    Transgenic animals are animals that have had a foreign gene deliberately inserted into their genome. Such, animals are most commonly created by micro-injection of DNA into the pronuclei of a fertilized egg which is implanted into the oviduct of a pseudopregnant surrogate mother. This results in the recipient giving birth to genetically modified offspring. 
  • Question 4
    1 / -0
    Which of the following biomolecules can be analysed by ELISA test?
    Solution
    Enzyme-linked immunosorbent assay (ELISA), also known as an enzyme immunoassay (EIA), is a biochemical technique used mainly in immunology for detecting and quantifying substances such as peptides, proteins, antibodies and hormones. They are termed as an analyte.
    So, the correct answer is option D.
  • Question 5
    1 / -0
    ELISA test is used to
    Solution
    ELISA is also known as enzyme-linked immunosorbent assay. It is used to detect the presence of proteinaceous antigen and antibody in a given sample. The sample containing a protein is attached to a surface. Antibody specific to the protein is added which agglutinates with it. The antibody is linked to an enzyme relevant to which enzyme's substrate is added. The enzyme acts on the substrate and shows detectable colour change which is an indicator of the presence of antigen in given sample.
    So, the correct answer is option D.
  • Question 6
    1 / -0
    Illegal and unlawful development of biomaterials without payment to inhabitants of their origin is called
    Solution

  • Question 7
    1 / -0
    Humulin is _________.
    Solution
    Humulin was the first therapeutic recombinant protein which established the feasibility of recombinant proteins.  Humulin N is a man-made insulin that is used to control high blood sugar in adults and children with diabetes mellitus.
    So, option D is the correct option.
  • Question 8
    1 / -0
    Transgenic plants are the ones
    Solution
    Transgenic plants are plants that have been genetically engineered, a breeding approach that uses recombinant DNA techniques to create plants with new characteristics. They are identified as a class of genetically modified organism (GMO).
    So the correct answer is option D.
  • Question 9
    1 / -0
    In an experiment the gene of bioluminescence from firefly has been successfully transferred into a plant as a result of which it started to glow. In the terminology of the molecular genetics, the plant is called ___________.
    Solution
    Transgenic plants are plants that have been genetically engineered, a breeding approach that uses recombinant DNA techniques to create plants with new characteristics. They are identified as a class of genetically modified organism (GMO). In this case, firefly's gene is transferred to the plant, hence the plant is called transgenic plant.

    So, the correct answer is 'Transgenic plant'.
  • Question 10
    1 / -0
    Figure given below depict the procedure for gene therapy. Pick up the disorders for which this technique has been applied successfully.

    Solution
    ADA deficiency or adenosine deaminase deficiency is a genetic disorder.
    Gene therapy is the transfer of the normal gene into body cells to correct a genetic defect. It can be used to treat genetic diseases like severe combined immunodeficiency. SCID is caused by a defect in the gene for the enzyme adenosine deaminase (ADA).
    These patients have non-functioning T lymphocytes and the patients are treated with injections of their white blood cells that have been engineered to carry the normal ADA alleles.
    So, the correct option is 'Adenosine Deaminase (ADA) Deficiency'
