  • Question 1
    1 / -0
    Which of the following technique use capture and detecting antibody?
    Solution
    • Sandwich ELISA is a less common variant of ELISA, but is highly efficient in sample antigen detection.
    •  It quantify antigens between two layers of antibodies i.e., capture and detection antibody.
    •  The antigen to be measured must contain at least two antigenic epitope capable of binding to antibody, since at least two antibodies act in the sandwich.
    So, the correct answer is option C.
  • Question 2
    1 / -0
    The modification of original genetic make-up is focussed by
    Solution
    Gene therapy is the method which uses genes to treat disease. This technique involves the introduction of normal genes into cells. This helps in replacing the function of the missing or defective ones in order to correct genetic disorders. There may be a mutant allele in the genetic composition of the organism. 
    Thus, the correct answer is option D. 
  • Question 3
    1 / -0
    Agrobacterium tumefaciens is most widely used for gene transfer because 
    Solution
    Agrobacterium tumefaciens naturally infects the wound sites in dicots causing the crown gall disease. It is capable of transferring T-DNA of the Tumour inducing (Ti) plasmid into the nucleus of infected cells. It will then integrate into the host genome and is transcribed, causing the crown gall disease. This property of tumor formation is exploited in biotechnology and hence Agrobacterium tumefaciens has become the most used method for plant transformation by gene transfer. Thus the correct answer is option C.
  • Question 4
    1 / -0
    Semi dwarf rice variety IR-$$8$$ was developed in
    Solution
    IR-8 is a high yielding semi-dwarf variety of rice that was developed by the International Rice Research Institute (IRRI), Philippines. In 1962, breeders at IRRI made crosses to introduce dwarfing genes from Taiwanese varieties such as Dee-geo-woo, Taichung Native 1 and Igeo-tse to tropical tall land races. In 1966, IR8, the first semi-dwarf, high yielding rice variety, was released for the tropical irrigated lowlands.
    Hence, the correct answer is ‘Philippines’.
  • Question 5
    1 / -0
    The human protein $$\alpha$$ -1 antitrypsin is obtained from _______.
    Solution
    • The $$\alpha$$ -1 antitrypsin deficiency is an inherited disorder that may cause lung disease and liver disease 
    • The transgenic sheep Tracy was developed by genetic modification to produce the protein $$\alpha$$ -1 antitrypsin in the milk. This is the human protein whose gene was introduced in the sheep for the commercial production of the protein which can be used for the treatment of respiratory infections. 
    Thus, the correct answer is option B. 
  • Question 6
    1 / -0
    Which of the following are not produced as transgenic animals?
    Solution
    Transgenic animals are those animals in which foreign gene is inserted into their genome. These are created by injecting foreign DNA in embryonic stem cell. Rat is the most common transgenic animal used in research due to short reproduction cycle. Transgenic pigs are used as a source of organs for transplants. Dolly, the sheep is the first transgenic animal. Transgenic rabbits are used to produce recombinant human C12 esterase inhibitor. Some other transgenic animals that have been produced are cow, goats, fish, etc. These animals are used to produce more protein in milk and meat, disease resistance, good quality wool and improvement in genetic traits. 
    Thus, the correct answer is option C.
  • Question 7
    1 / -0
    More than $$95\%$$ of transgenic animals are ________.
    Solution
    B. Mice
    Solution : A transgenic organism is the organism that carries recombinant DNA in it. More than 95% transgenic animals are mice.
    So the correct answer is "Mice".
  • Question 8
    1 / -0
    Pusa shubhra is a variety of
    Solution
    Pusa shubhra is a variety of cauliflower. It belongs to third maturity group.  Curds are compact, slightly conical, creamish white in colour, non-ricey and non-leafy. It is suitable for rainy season. Curds do not fade even under delayed harvesting and storage
    So, the correct answer is 'Cauliflower'
  • Question 9
    1 / -0
    High levels of aspartic acid, low nitrogen and sugar content in maize plants prevent the attack by
    Solution
    • Maize plant exhibits an example of the development of pest resistance due to biochemical characters.
    • Low nitrogen, sugar and high aspartic acid impart the plants resistance to stem borers which is one of the most serious pests of these plants. 
    • Cotton plants exhibit the resistant to jassids due to the presence of hairy leaves. Aphids affect plants of mustard family and beans. 
    So, the correct answer is option D.
  • Question 10
    1 / -0
    Transgenic animals are extensively used for all the following procedures except
    Solution
    • The technique of cleaning the environment with the help of microbes, plant, and animal species is called bioremediation. 
    • The organisms involved in bioremediation have the ability to break down harmful toxic components of the environment. 
    • The genes responsible for the breakdown of toxic components are selected and introduced into other organisms by the process of transgenesis. 
    • Chemical safety, vaccine safety, and toxicity test all are done on transgenic animals.
    Thus, the correct answer is option A.
