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

In transgenics, expression of transgene in target tissue is determined by?

  1. Reporter

  2. Enhancer

  3. Transgene

  4. Promotor
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In transgenic studies, a promoter is a regulatory DNA sequence that initiates transcription of a particular gene, thus determining where and to what extent the transgene is expressed in the target tissue.

Match the column.

List-I List-II
(Transgenic plant) (Resistance to)
A) Papaya I) Herbicides
B) Bt cotton II) Ring spot virus
C) Roundup ready soya bean III) Phytophthora
D) Tomato IV) Insects
V) Pseudomonas

  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
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Matching the transgenic plants to their respective resistances: Papaya is engineered for resistance to ring spot virus (A-II). Bt cotton is engineered for resistance to insects (B-IV). Roundup ready soybean is resistant to glyphosate herbicides (C-I). Tomato has been modified for delayed ripening or other traits like resistance to Pseudomonas (D-V). Thus, the correct pairing is A-II, B-IV, C-I, D-V.

Genetically modified bacteria are used in 

  1. Medicine

  2. Patrolling

  3. Cropping

  4. All of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
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
Reveal answer Fill a bubble to check yourself
D Correct answer
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'

Bioremediation is

  1. Genetically engineered organisms capable of producing pharmaceuticals

  2. Biological control

  3. Biopurification of environment

  4. Both B and C
Reveal answer Fill a bubble to check yourself
C Correct answer
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
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Transgenic mice are widely used as models to test the safety of vaccines, such as the polio vaccine, before they are administered to humans, reducing the need for using monkeys.
