What is the primary goal of genetic engineering for disease resistance?

  1. To enhance the immune system's ability to fight off diseases

  2. To introduce genes that confer resistance to specific diseases

  3. To modify genes responsible for disease susceptibility

  4. To develop new vaccines and treatments for diseases


Correct Option: B
Explanation:

Genetic engineering aims to introduce genes that provide resistance to specific diseases, thereby enhancing the organism's ability to combat and overcome infections.

Which technique is commonly used to introduce foreign genes into an organism for disease resistance?

  1. Gene editing (CRISPR-Cas9)

  2. Transgenesis

  3. Gene therapy

  4. Selective breeding


Correct Option: B
Explanation:

Transgenesis involves the insertion of foreign genes into the genome of an organism, allowing the expression of those genes and conferring specific traits, including disease resistance.

What is the role of marker genes in genetic engineering for disease resistance?

  1. To confer resistance to specific diseases

  2. To facilitate the identification and selection of transformed cells

  3. To regulate the expression of disease resistance genes

  4. To enhance the immune response against pathogens


Correct Option: B
Explanation:

Marker genes are used to identify and select cells that have successfully undergone genetic transformation, allowing researchers to isolate and propagate cells with the desired disease resistance traits.

Which type of genetic engineering approach involves modifying an organism's own genes to enhance disease resistance?

  1. Cisgenesis

  2. Transgenesis

  3. Gene editing (CRISPR-Cas9)

  4. Genome editing


Correct Option: A
Explanation:

Cisgenesis involves modifying an organism's own genes, typically by introducing genetic variations or regulatory elements, to enhance disease resistance without introducing foreign genes from other species.

What is the main advantage of using gene editing techniques like CRISPR-Cas9 in genetic engineering for disease resistance?

  1. Increased accuracy and precision in gene modification

  2. Ability to target specific genes and make precise changes

  3. Reduced risk of introducing foreign genes

  4. Enhanced efficiency and speed of genetic engineering


Correct Option: B
Explanation:

Gene editing techniques like CRISPR-Cas9 allow researchers to target specific genes and make precise changes, enabling the correction of disease-causing mutations or the introduction of disease resistance genes with high accuracy.

Which ethical consideration is often raised in the context of genetic engineering for disease resistance?

  1. Potential environmental impact of genetically modified organisms

  2. Concerns about the unintended consequences of altering genetic material

  3. Questions about the long-term effects of genetic modifications on human health

  4. All of the above


Correct Option: D
Explanation:

Genetic engineering for disease resistance raises ethical considerations related to the potential environmental impact, unintended consequences of genetic modifications, and long-term effects on human health, requiring careful assessment and regulation.

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

  1. Transgenesis

  2. Cisgenesis

  3. Gene editing

  4. Genome editing


Correct Option: A
Explanation:

Transgenesis refers to the process of introducing genes from one species into the genome of another species, allowing the recipient organism to express and potentially benefit from the introduced genes.

Which regulatory agency in the United States is responsible for overseeing the safety and efficacy of genetically modified organisms, including those engineered for disease resistance?

  1. Food and Drug Administration (FDA)

  2. Environmental Protection Agency (EPA)

  3. Centers for Disease Control and Prevention (CDC)

  4. National Institutes of Health (NIH)


Correct Option: A
Explanation:

The Food and Drug Administration (FDA) is the primary regulatory agency in the United States responsible for ensuring the safety and efficacy of genetically modified organisms, including those engineered for disease resistance, before they can be introduced into the market.

What is the term used to describe the process of modifying an organism's own genes without introducing foreign genes?

  1. Cisgenesis

  2. Transgenesis

  3. Gene editing

  4. Genome editing


Correct Option: A
Explanation:

Cisgenesis involves modifying an organism's own genes, typically by introducing genetic variations or regulatory elements, without introducing foreign genes from other species.

Which type of genetic engineering approach involves introducing genes from closely related species into an organism?

  1. Cisgenesis

  2. Transgenesis

  3. Gene editing

  4. Genome editing


Correct Option: A
Explanation:

Cisgenesis involves introducing genes from closely related species into an organism, typically with the aim of enhancing disease resistance or other desirable traits.

What is the term used to describe the process of modifying an organism's genome at specific locations using targeted nucleases?

  1. Cisgenesis

  2. Transgenesis

  3. Gene editing

  4. Genome editing


Correct Option: C
Explanation:

Gene editing refers to the process of modifying an organism's genome at specific locations using targeted nucleases, allowing researchers to make precise changes to the DNA sequence.

Which type of genetic engineering approach involves introducing genes from unrelated species into an organism?

  1. Cisgenesis

  2. Transgenesis

  3. Gene editing

  4. Genome editing


Correct Option: B
Explanation:

Transgenesis involves introducing genes from unrelated species into an organism, allowing the recipient organism to express and potentially benefit from the introduced genes.

What is the term used to describe the process of modifying an organism's entire genome?

  1. Cisgenesis

  2. Transgenesis

  3. Gene editing

  4. Genome editing


Correct Option: D
Explanation:

Genome editing refers to the process of modifying an organism's entire genome, allowing researchers to make broad changes to the genetic makeup of the organism.

Which type of genetic engineering approach involves introducing genes from the same species into an organism?

  1. Cisgenesis

  2. Transgenesis

  3. Gene editing

  4. Genome editing


Correct Option: A
Explanation:

Cisgenesis involves introducing genes from the same species into an organism, typically with the aim of enhancing disease resistance or other desirable traits.

What is the term used to describe the process of modifying an organism's genome using homologous recombination?

  1. Cisgenesis

  2. Transgenesis

  3. Gene editing

  4. Genome editing


Correct Option: D
Explanation:

Genome editing refers to the process of modifying an organism's genome using homologous recombination, allowing researchers to make precise changes to the DNA sequence.
