What is the process of transferring genetic material from one organism to another called?

  1. Genetic Engineering

  2. Gene Therapy

  3. Genetic Modification

  4. Transgenesis


Correct Option: A
Explanation:

Genetic engineering involves the deliberate modification of an organism's genetic material to achieve a desired trait or characteristic.

Which enzyme is commonly used to cut DNA at specific sequences?

  1. Restriction Enzyme

  2. Polymerase

  3. Ligase

  4. Helicase


Correct Option: A
Explanation:

Restriction enzymes are used to cut DNA at specific sequences, allowing for the manipulation and recombination of genetic material.

What is the process of inserting a foreign gene into the genome of an organism called?

  1. Gene Targeting

  2. Transgenesis

  3. Gene Editing

  4. Genetic Modification


Correct Option: B
Explanation:

Transgenesis involves the introduction of a foreign gene into the genome of an organism, resulting in the expression of that gene and its associated trait.

Which technology allows for the precise editing of DNA sequences?

  1. CRISPR-Cas9

  2. Gene Therapy

  3. Transgenesis

  4. Genetic Engineering


Correct Option: A
Explanation:

CRISPR-Cas9 is a gene-editing technology that allows for the precise modification of DNA sequences, enabling targeted changes to an organism's genome.

What is the term used to describe an organism that has had its genetic material altered?

  1. Genetically Modified Organism (GMO)

  2. Transgenic Organism

  3. Genetically Engineered Organism (GEO)

  4. Recombinant Organism


Correct Option: A
Explanation:

A Genetically Modified Organism (GMO) is an organism whose genetic material has been altered using genetic engineering techniques.

Which technique involves the transfer of genetic material between different species?

  1. Hybridization

  2. Transgenesis

  3. Gene Therapy

  4. Genetic Engineering


Correct Option: B
Explanation:

Transgenesis involves the transfer of genetic material between different species, allowing for the introduction of new traits or characteristics into an organism.

What is the primary goal of genetic engineering in agriculture?

  1. Increased Crop Yield

  2. Enhanced Nutritional Value

  3. Resistance to Pests and Diseases

  4. Improved Drought Tolerance


Correct Option: A
Explanation:

Genetic engineering in agriculture aims to increase crop yield, improve nutritional value, enhance resistance to pests and diseases, and increase drought tolerance.

Which ethical concern is often raised in relation to genetic engineering?

  1. Environmental Impact

  2. Unintended Consequences

  3. Loss of Biodiversity

  4. Food Safety


Correct Option:
Explanation:

Genetic engineering raises ethical concerns related to environmental impact, unintended consequences, loss of biodiversity, and food safety.

What is the process of using genetic engineering to treat genetic disorders called?

  1. Gene Therapy

  2. Genetic Modification

  3. Transgenesis

  4. Genetic Engineering


Correct Option: A
Explanation:

Gene therapy involves the use of genetic engineering to treat genetic disorders by introducing functional genes into an organism to correct or compensate for defective genes.

Which regulatory agency is responsible for overseeing the safety of genetically modified organisms in the United States?

  1. Food and Drug Administration (FDA)

  2. Environmental Protection Agency (EPA)

  3. Department of Agriculture (USDA)

  4. Centers for Disease Control and Prevention (CDC)


Correct Option: A
Explanation:

The Food and Drug Administration (FDA) is responsible for overseeing the safety of genetically modified organisms in the United States.

What is the term used to describe the process of inserting a gene into a cell?

  1. Transfection

  2. Transformation

  3. Transduction

  4. Conjugation


Correct Option: A
Explanation:

Transfection is the process of introducing genetic material into a cell, typically using a vector such as a plasmid or virus.

Which technology allows for the rapid sequencing of DNA?

  1. Polymerase Chain Reaction (PCR)
