What is the primary technique used to create genetically modified crops?

  1. Selective Breeding

  2. Genetic Modification

  3. Hybridization

  4. Natural Selection


Correct Option: B
Explanation:

Genetic modification involves the direct manipulation of an organism's genes using recombinant DNA technology.

Which of the following is a potential benefit of genetically modified crops?

  1. Increased Resistance to Pests and Diseases

  2. Enhanced Nutritional Content

  3. Reduced Pesticide Usage

  4. All of the Above


Correct Option: D
Explanation:

Genetically modified crops can be engineered to possess traits that enhance their resistance to pests and diseases, improve their nutritional content, and reduce the need for pesticides.

What is the primary concern associated with the cultivation of genetically modified crops?

  1. Loss of Biodiversity

  2. Gene Transfer to Wild Relatives

  3. Increased Pesticide Resistance in Pests

  4. All of the Above


Correct Option: D
Explanation:

Cultivation of genetically modified crops raises concerns about potential impacts on biodiversity, gene transfer to wild relatives, and the development of resistance in pests to the modified traits.

Which international organization is responsible for regulating the trade of genetically modified crops?

  1. World Trade Organization (WTO)

  2. Food and Agriculture Organization (FAO)

  3. World Health Organization (WHO)

  4. Convention on Biological Diversity (CBD)


Correct Option: A
Explanation:

The World Trade Organization (WTO) is responsible for regulating the trade of genetically modified crops through its Sanitary and Phytosanitary (SPS) Agreement.

What is the term used to describe the process of introducing a gene from one organism into another?

  1. Transgenesis

  2. Hybridization

  3. Selective Breeding

  4. Mutation


Correct Option: A
Explanation:

Transgenesis refers to the process of transferring genetic material from one organism to another, resulting in the creation of a genetically modified organism (GMO).

Which technology is commonly used to insert genes into plant cells?

  1. Polymerase Chain Reaction (PCR)

  2. Gel Electrophoresis

  3. Agrobacterium-Mediated Transformation

  4. DNA Microarrays


Correct Option: C
Explanation:

Agrobacterium-mediated transformation is a widely used method for introducing genes into plant cells, utilizing the natural ability of Agrobacterium bacteria to transfer DNA into plant cells.

What is the term used to describe the unintended transfer of genes from genetically modified crops to wild relatives?

  1. Gene Flow

  2. Genetic Drift

  3. Gene Silencing

  4. Epigenetics


Correct Option: A
Explanation:

Gene flow refers to the transfer of genetic material from one population to another, including the unintended transfer of genes from genetically modified crops to wild relatives through processes like pollination or seed dispersal.

Which regulatory agency in the United States is responsible for evaluating the safety of genetically modified crops?

  1. Environmental Protection Agency (EPA)

  2. Food and Drug Administration (FDA)

  3. Department of Agriculture (USDA)

  4. All of the Above


Correct Option: D
Explanation:

In the United States, the Environmental Protection Agency (EPA), Food and Drug Administration (FDA), and Department of Agriculture (USDA) share the responsibility for evaluating the safety of genetically modified crops.

What is the term used to describe the process of modifying an organism's DNA to produce a desired trait?

  1. Genetic Engineering

  2. Selective Breeding

  3. Hybridization

  4. Mutation


Correct Option: A
Explanation:

Genetic engineering involves the direct manipulation of an organism's DNA to introduce or modify specific genes, resulting in the creation of genetically modified organisms (GMOs).

Which international agreement aims to promote the safe and sustainable use of genetically modified organisms?

  1. Cartagena Protocol on Biosafety

  2. Kyoto Protocol

  3. Montreal Protocol

  4. Paris Agreement


Correct Option: A
Explanation:

The Cartagena Protocol on Biosafety is an international agreement that aims to promote the safe and sustainable use of genetically modified organisms (GMOs) by establishing a framework for their transboundary movement and handling.

What is the term used to describe the process of using genetic markers to identify and select individuals with desired traits?

  1. Genetic Screening

  2. Selective Breeding

  3. Hybridization

  4. Mutation


Correct Option: A
Explanation:

Genetic screening involves the analysis of genetic markers to identify individuals with specific genetic variations associated with desired traits, allowing for selective breeding or other genetic interventions.

Which technology is commonly used to detect and quantify genetically modified organisms (GMOs)?

  1. Polymerase Chain Reaction (PCR)

  2. Gel Electrophoresis

  3. DNA Microarrays

  4. All of the Above


Correct Option: D
Explanation:

Polymerase Chain Reaction (PCR), Gel Electrophoresis, and DNA Microarrays are commonly used techniques for detecting and quantifying genetically modified organisms (GMOs) by analyzing their specific genetic modifications.

What is the term used to describe the process of introducing a gene from one species into another?

  1. Transgenesis

  2. Hybridization

  3. Selective Breeding

  4. Mutation


Correct Option: A
Explanation:

Transgenesis refers to the process of transferring genetic material from one species to another, resulting in the creation of a genetically modified organism (GMO) with characteristics from both species.

Which international organization is responsible for coordinating global efforts to promote sustainable agriculture and food security?

  1. Food and Agriculture Organization (FAO)

  2. World Trade Organization (WTO)

  3. World Health Organization (WHO)

  4. Convention on Biological Diversity (CBD)


Correct Option: A
Explanation:

The Food and Agriculture Organization (FAO) is the specialized agency of the United Nations responsible for leading international efforts to defeat hunger, improve nutrition, and promote sustainable agriculture and food security.

What is the term used to describe the process of modifying an organism's DNA using gene editing techniques?

  1. Genome Editing

  2. Genetic Engineering

  3. Selective Breeding

  4. Hybridization


Correct Option: A
Explanation:

Genome editing refers to the use of molecular tools to make precise changes to an organism's DNA, allowing for targeted modifications of specific genes or genetic regions.
