Transgenic plants are 

  1. Plants having no gene

  2. Plants in which gene are present in an opposite or transposition

  3. Plants in which genes have no function to perform

  4. Plants in which genes of another organism have been implanted


Correct Option: D
Explanation:

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 organisms. Transgenic plants can be created by inserting genes of other organisms. 

So, the correct answer is 'plants in which genes of another organisms have been implanted'

Giant Mouse has been produced through

  1. Tissue culture

  2. Gene differentiation

  3. Gene manipulation

  4. All the above


Correct Option: C

Pseudomonas putida cleans

  1. Oils spills

  2. Sewage

  3. Hides

  4. None of the above


Correct Option: A
Explanation:

Pseudomonas putida is a gram-negative bacteria that helps in cleaning the oil spills.

So the correct option is A.

Bioremediation is

  1. Genetically engineered organisms capable of producing pharmaceuticals

  2. Biological control

  3. Biopurification of environment

  4. Both B and C


Correct Option: C
Explanation:

Bioremediation is the process of treating the contaminated water, soil and subsurface material by altering the environmental conditions in which the growth of microorganisms is stimulated.

So the correct option is C.
