Genetically modified bacteria are used in 

biology genetics of the future genetically modified animals and crops transgenic organisms biotechnology and its applications

  1. Medicine

  2. Patrolling

  3. Cropping

  4. All of the above

Show answer
Correct Option: A
Explanation:

Genetically modified bacteria were the first organisms to be modified in the laboratory, due to their simple genetics. These organisms are now used for several purposes, and are particularly important in producing large amounts of pure human proteins for use in medicine. The drug industry has made use of this discovery in its quest to produce medication for diabetes. 

Transgenic plants are 

biology genetics of the future genetically modified animals and crops transgenic organisms biotechnology and its applications

  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

Show answer
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

biology genetics of the future genetically modified animals and crops transgenic organisms biotechnology and its applications

  1. Tissue culture

  2. Gene differentiation

  3. Gene manipulation

  4. All the above

Show answer
Correct Option: C

Pseudomonas putida cleans

biology genetics of the future genetically modified animals and crops transgenic organisms biotechnology and its applications

  1. Oils spills

  2. Sewage

  3. Hides

  4. None of the above

Show answer
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

biology genetics of the future genetically modified animals and crops transgenic organisms biotechnology and its applications

  1. Genetically engineered organisms capable of producing pharmaceuticals

  2. Biological control

  3. Biopurification of environment

  4. Both B and C

Show answer
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.
