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

  1. Gene Therapy

  2. Genetic Engineering

  3. Recombinant DNA Technology

  4. Gene Cloning


Correct Option: B
Explanation:

Genetic engineering involves the deliberate modification of an organism's genetic material to achieve desired traits or characteristics.

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

  1. Polymerase

  2. Ligase

  3. Restriction Enzyme

  4. Helicase


Correct Option: C
Explanation:

Restriction enzymes are used to cut DNA at specific recognition sequences, allowing for targeted manipulation of genetic material.

What is the process of inserting a foreign gene into a host organism's genome?

  1. Transduction

  2. Transformation

  3. Transfection

  4. Gene Editing


Correct Option: B
Explanation:

Transformation involves the uptake of foreign DNA by a host organism, resulting in the integration of the new genetic material into the host's genome.

Which organism is commonly used as a host for cloning vectors?

  1. E. coli

  2. Yeast

  3. Human Cells

  4. Animal Cells


Correct Option: A
Explanation:

E. coli is a widely used host organism for cloning vectors due to its rapid growth, ease of genetic manipulation, and well-studied genetic system.

What is the process of amplifying a specific DNA sequence using a thermostable DNA polymerase?

  1. PCR (Polymerase Chain Reaction)

  2. DNA Sequencing

  3. Gel Electrophoresis

  4. Southern Blotting


Correct Option: A
Explanation:

PCR involves repeated cycles of heating and cooling to denature and anneal DNA strands, resulting in the exponential amplification of a specific DNA sequence.

Which technique allows for the separation of DNA fragments based on their size?

  1. PCR (Polymerase Chain Reaction)

  2. DNA Sequencing

  3. Gel Electrophoresis

  4. Southern Blotting


Correct Option: C
Explanation:

Gel electrophoresis separates DNA fragments based on their size, allowing for the analysis and identification of specific DNA sequences.

What is the process of detecting a specific DNA sequence using a labeled probe?

  1. PCR (Polymerase Chain Reaction)

  2. DNA Sequencing

  3. Gel Electrophoresis

  4. Southern Blotting


Correct Option: D
Explanation:

Southern blotting involves the transfer of DNA fragments from a gel onto a membrane, followed by hybridization with a labeled probe to detect the presence of a specific DNA sequence.

Which technique allows for the sequencing of DNA?

  1. PCR (Polymerase Chain Reaction)

  2. DNA Sequencing

  3. Gel Electrophoresis

  4. Southern Blotting


Correct Option: B
Explanation:

DNA sequencing determines the order of nucleotides in a DNA molecule, providing valuable information about the genetic makeup of an organism.

What is the process of modifying an organism's genome using engineered nucleases?

  1. Gene Therapy

  2. Genetic Engineering

  3. Recombinant DNA Technology

  4. Gene Editing


Correct Option: D
Explanation:

Gene editing involves the use of engineered nucleases to make precise changes to an organism's genome, allowing for targeted manipulation of genetic traits.

Which ethical consideration is often associated with genetic engineering?

  1. Environmental Impact

  2. Animal Welfare

  3. Genetically Modified Organisms (GMOs)

  4. All of the above


Correct Option: D
Explanation:

Genetic engineering raises ethical considerations related to environmental impact, animal welfare, and the potential risks and benefits of genetically modified organisms (GMOs).

What is the term for an organism that has been genetically modified?

  1. Transgenic Organism

  2. Genetically Modified Organism (GMO)

  3. Recombinant Organism

  4. All of the above


Correct Option: D
Explanation:

Transgenic organism, genetically modified organism (GMO), and recombinant organism are all terms used to describe an organism that has been genetically modified through the introduction of foreign genetic material.

Which international agreement regulates the transboundary movement of living modified organisms?

  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 regulates the transboundary movement of living modified organisms (LMOs) and aims to ensure the safe handling, transport, and use of LMOs.

What is the term for the process of transferring genetic material from one cell to another?

  1. Transduction

  2. Transformation

  3. Transfection

  4. Conjugation


Correct Option: A
Explanation:

Transduction is the process by which genetic material is transferred from one cell to another by a virus.

Which technique allows for the production of large quantities of a specific protein?

  1. PCR (Polymerase Chain Reaction)

  2. DNA Sequencing

  3. Gel Electrophoresis

  4. Recombinant Protein Production


Correct Option: D
Explanation:

Recombinant protein production involves the use of genetic engineering techniques to produce large quantities of a specific protein in a host organism.

What is the term for the process of introducing genetic material into a cell using a vector?

  1. Transduction

  2. Transformation

  3. Transfection

  4. Conjugation


Correct Option: C
Explanation:

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