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

  1. Genetic Modification

  2. Gene Editing

  3. Transgenesis

  4. Genetic Engineering


Correct Option: D
Explanation:

Genetic Engineering is the process of transferring genes from one organism to another, resulting in the creation of a genetically modified organism (GMO).

Which technique is used to insert a foreign gene into a host organism?

  1. Polymerase Chain Reaction (PCR)

  2. Gene Gun

  3. Southern Blotting

  4. Gel Electrophoresis


Correct Option: B
Explanation:

Gene Gun is a device that uses high-pressure helium to shoot tiny particles coated with DNA into plant cells, allowing for the insertion of foreign genes.

What is the role of restriction enzymes in genetic engineering?

  1. They cut DNA at specific sequences.

  2. They amplify DNA.

  3. They separate DNA fragments.

  4. They detect mutations in DNA.


Correct Option: A
Explanation:

Restriction enzymes are enzymes that recognize and cut DNA at specific nucleotide sequences, enabling the isolation and manipulation of specific DNA fragments.

Which organism was the first to have its genome sequenced?

  1. Escherichia coli

  2. Caenorhabditis elegans

  3. Drosophila melanogaster

  4. Homo sapiens


Correct Option: A
Explanation:

Escherichia coli was the first organism to have its genome sequenced in 1995, marking a significant milestone in genomics.

CRISPR-Cas9 is a gene-editing tool that utilizes which type of RNA?

  1. Transfer RNA (tRNA)

  2. Messenger RNA (mRNA)

  3. Small Interfering RNA (siRNA)

  4. Guide RNA (gRNA)


Correct Option: D
Explanation:

CRISPR-Cas9 utilizes Guide RNA (gRNA) to target and cut specific DNA sequences, enabling precise genome editing.

What is the term for an organism that has had its genetic material altered using genetic engineering techniques?

  1. Transgenic Organism

  2. Genetically Modified Organism (GMO)

  3. Recombinant Organism

  4. Cloned Organism


Correct Option: B
Explanation:

Genetically Modified Organism (GMO) is the term used to describe an organism whose genetic material has been altered through genetic engineering techniques.

Which regulatory agency in the United States is responsible for evaluating the safety of GMOs?

  1. Environmental Protection Agency (EPA)

  2. Food and Drug Administration (FDA)

  3. Centers for Disease Control and Prevention (CDC)

  4. National Institutes of Health (NIH)


Correct Option: B
Explanation:

The Food and Drug Administration (FDA) is the regulatory agency responsible for evaluating the safety of GMOs in the United States.

What is the primary concern regarding the use of GMOs in agriculture?

  1. Increased pesticide resistance

  2. Reduced crop yields

  3. Loss of biodiversity

  4. Allergic reactions in consumers


Correct Option: A
Explanation:

The primary concern regarding the use of GMOs in agriculture is the potential for increased pesticide resistance, leading to reduced effectiveness of pesticides and environmental impacts.

Which crop was the first genetically modified crop to be commercialized?

  1. Soybean

  2. Corn

  3. Cotton

  4. Canola


Correct Option: A
Explanation:

Soybean was the first genetically modified crop to be commercialized in 1996, followed by corn and cotton.

What is the term for the process of introducing a gene from one species into another species?

  1. Transgenesis

  2. Gene Transfer

  3. Genetic Modification

  4. Cloning


Correct Option: A
Explanation:

Transgenesis is the process of introducing a gene from one species into another species, resulting in the creation of a transgenic organism.

Which technique is used to amplify a specific region of DNA?

  1. Polymerase Chain Reaction (PCR)

  2. Restriction Enzyme Digestion

  3. Gel Electrophoresis

  4. Southern Blotting


Correct Option: A
Explanation:

Polymerase Chain Reaction (PCR) is a technique used to amplify a specific region of DNA by repeatedly copying it, resulting in millions of copies of the target DNA sequence.

What is the term for an organism that has had its own genetic material removed and replaced with genetic material from another organism?

  1. Transgenic Organism

  2. Genetically Modified Organism (GMO)

  3. Knockout Organism

  4. Knockin Organism


Correct Option: C
Explanation:

Knockout Organism is an organism that has had its own genetic material removed, typically a specific gene, through genetic engineering techniques.

Which international agreement aims to ensure the safe transfer, handling, and use of living modified organisms (LMOs)?

  1. Kyoto Protocol

  2. Montreal Protocol

  3. Cartagena Protocol on Biosafety

  4. Paris Agreement


Correct Option: C
Explanation:

The Cartagena Protocol on Biosafety is an international agreement that aims to ensure the safe transfer, handling, and use of living modified organisms (LMOs) resulting from modern biotechnology.

What is the term for the process of modifying an organism's genome using targeted DNA breaks and subsequent repair mechanisms?

  1. Gene Editing

  2. Genetic Engineering

  3. Transgenesis

  4. Cloning


Correct Option: A
Explanation:

Gene Editing is the process of modifying an organism's genome using targeted DNA breaks and subsequent repair mechanisms, allowing for precise changes to the genetic code.

Which gene-editing tool utilizes a protein-DNA complex to target and modify specific DNA sequences?

  1. CRISPR-Cas9

  2. TALENs

  3. Zinc Finger Nucleases (ZFNs)

  4. Meganucleases


Correct Option: B
Explanation:

TALENs (Transcription Activator-Like Effector Nucleases) are gene-editing tools that utilize a protein-DNA complex to target and modify specific DNA sequences.
