Correct answer Carries: 4.

Wrong Answer Carries: -1.

What is the primary goal of biotechnology in the field of agriculture?

Increase pesticide usage
Enhance crop yield and resistance
Reduce soil fertility
Promote monoculture
2

Biotechnology aims to improve crop yield, resistance to pests, and environmental stress tolerance.

Which enzyme is deficient in individuals with ADA deficiency?

Adenosine deaminase
Glucose-6-phosphate dehydrogenase
Lactase
Phenylalanine hydroxylase
1

Adenosine deaminase deficiency affects the immune system, making gene therapy necessary.

Which biotechnological technique is used to fuse protoplasts from different plant species?

Micropropagation
Somatic hybridization
Tissue culture
Gene therapy
2

Somatic hybridization is the fusion of protoplasts from different plant species to form a hybrid.

Which organism's protoplast fusion resulted in the formation of 'Pomato'?

Potato and tomato
Tomato and maize
Potato and wheat
Maize and tomato
1

Pomato is produced by the fusion of protoplasts from potato and tomato plants through somatic hybridization.

Which term describes plants produced through genetic engineering techniques?

Hybrids
Transgenic plants
Somaclones
Grafted plants
2

Transgenic plants are produced using genetic engineering techniques to introduce new traits.

Which term describes the introduction of foreign DNA into an organism to create a genetically modified organism?

Hybridization
Recombinant DNA technology
Somatic hybridization
Gene therapy
2

Recombinant DNA technology involves introducing foreign DNA into an organism to create genetically modified organisms.

Which organism is commonly used for the production of recombinant human insulin?

Saccharomyces cerevisiae
Bacillus subtilis
Escherichia coli
Agrobacterium tumefaciens
3

Escherichia coli is commonly used to produce recombinant human insulin through genetic engineering.

Which of the following statements about Bt cotton is correct?

Bt cotton produces Cry proteins toxic to insect pests.
Bt cotton is developed using Agrobacterium tumefaciens.
Bt cotton is resistant to bacterial infections.
Bt cotton increases soil fertility.
1

Bt cotton produces Cry proteins derived from Bacillus thuringiensis, which are toxic to specific insect pests.

Which of the following is correct about biopiracy?

Biopiracy refers to the legal use of biological resources with permission.
Biopiracy is the exploitation of biological resources without proper authorization.
Biopiracy is related only to the pharmaceutical industry.
Biopiracy promotes biodiversity conservation.
2

Biopiracy is the unauthorized exploitation of biological resources, often leading to the commercial benefit of one party without fair compensation to the source region.

Which of the following is correct about Agrobacterium tumefaciens in plant biotechnology?

Agrobacterium tumefaciens is used to produce antibiotics in plants.
Agrobacterium tumefaciens acts as a vector for gene transfer in plants.
Agrobacterium tumefaciens is a viral vector used in animals.
Agrobacterium tumefaciens produces Bt toxin in plants.
2

Agrobacterium tumefaciens is a bacterium that acts as a vector for transferring genes into plants using its Ti plasmid.
