  1. A-II, B-V, C-I, D-IF

  2. A-II, B-III, C-IV, D-I

  3. A-III, B-I, C-V, D-II

  4. A-II, B-IV, C-I, D-V


Correct Option: A

Genetically modified bacteria are used in 

  1. Medicine

  2. Patrolling

  3. Cropping

  4. All of the above


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 

  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.

Genetic engineering has been successfully used for producing

  1. Transgenic models for studying new treatments for certain cardiac diseases

  2. Transgenic cow, Rosie, which produces high fat milk for making ghee

  3. Animals like bulls for farm work as they have super power

  4. Transgenic mice for testing safety of polio vaccine before use in humans


Correct Option: D

Genetically engineered microorganism used successfully in bioremediation of oil spills is

  1. Trichoderma

  2. Xanthomonas

  3. Bacillus

  4. Pseudomonas


Correct Option: D

Maximum number of existing transgenic animals is of

  1. Cow

  2. Pig

  3. Mice

  4. Fish


Correct Option: C

Which technique made it possible to genetically engineer living organisms ___________________.

  1. Recombinant DNA techniques

  2. Heavy isotope labelling

  3. X-ray diffraction

  4. Hybridisation


Correct Option: A

Which transgenic animal has been given human genes for organ transplantation into humans without risk of rejection?

  1. Cow

  2. Sheep

  3. Goat

  4. Pig


Correct Option: D

Transgenic animals are generally produced for all of the following needs except

  1. Testing of chemical safety

  2. Testing of vaccine safety

  3. Stimulation of pathogenicity

  4. Production of pharmacologically important proteins


Correct Option: C

One of the advantages of developing transgenic mice is that it is very useful

  1. To study vaccine safety

  2. In producing new varieties of mice

  3. In developing a show piece example

  4. In gene targeting


Correct Option: A

Which is correct regarding genetically engineered insulin using E. coli ________________.

  1. Difficult to purify

  2. Obtained in large unlimited quantities

  3. Possibility of transmission of animal diseases

  4. Insulin obtained varies in chemical structure


Correct Option: B

Which best describes a transgenic organism ?

  1. One that act as the donor for DNA to be moved into another organism

  2. One produced by cloning a mutant cell

  3. One that contains a foreign gene and is free- living in the environment

  4. Any genetically modified organism- resulting from laboratory research


Correct Option: C
Explanation:

Transgenic Organism or Genetically Modified Organisms (GMO) is an organism whose genetic material has been altered using genetic engineering techniques. Bacteria are the easiest organism to engineer and have been used for research, food production, industrial protein purification etc. There is a potential to use them for environmental purposes or as medicines.

So, the correct option is 'One that contains a foreign gene and is free-living in the environment'.

Genes found in plants and animals that are of actual or potential value to people are known as

  1. genetic resources

  2. biotic resources

  3. oceanic resources

  4. natural resources


Correct Option: A
Explanation:

There are various genes that are found in animals and pants that are of important use for the humans. These genes are extracted and then introduced into organisms by genetic engineering.

These genes are known as genetic resources.
So, the correct option is 'genetic resources'
