Which technique allows scientists to modify an organism's DNA by inserting or removing specific genes?

  1. Gene Editing

  2. Genetic Engineering

  3. Genome Sequencing

  4. Gene Therapy


Correct Option: B
Explanation:

Genetic Engineering involves the deliberate modification of an organism's DNA to introduce or remove specific genes, altering its traits.

In medicine, gene therapy aims to treat diseases by:

  1. Replacing faulty genes with functional ones

  2. Introducing genes that produce therapeutic proteins

  3. Correcting genetic mutations

  4. All of the above


Correct Option: D
Explanation:

Gene therapy encompasses various approaches to treat diseases by replacing faulty genes, introducing genes that produce therapeutic proteins, and correcting genetic mutations.

Which genetic engineering technique involves transferring genes from one organism to another?

  1. Gene Editing

  2. Genome Sequencing

  3. Transgenesis

  4. Gene Therapy


Correct Option: C
Explanation:

Transgenesis involves the transfer of genes from one organism to another, enabling the recipient organism to express the transferred genes and their associated traits.

In agriculture, genetically modified crops are engineered to:

  1. Resist pests and diseases

  2. Enhance nutritional value

  3. Tolerate harsh environmental conditions

  4. All of the above


Correct Option: D
Explanation:

Genetic engineering in agriculture aims to develop crops with improved resistance to pests and diseases, enhanced nutritional value, and tolerance to harsh environmental conditions, leading to increased crop yields and food security.

Which technology enables the precise editing of DNA sequences?

  1. CRISPR-Cas9

  2. Gene Editing

  3. Genome Sequencing

  4. Transgenesis


Correct Option: A
Explanation:

CRISPR-Cas9 is a revolutionary gene editing technology that allows scientists to make precise changes to DNA sequences, enabling targeted modifications and corrections.

Which ethical concern arises from the use of gene editing in humans?

  1. Potential for unintended consequences

  2. Unequal access to genetic enhancements

  3. Blurring the line between therapy and enhancement

  4. All of the above


Correct Option: D
Explanation:

The use of gene editing in humans raises ethical concerns regarding potential unintended consequences, unequal access to genetic enhancements, and the blurring of the line between therapy and enhancement.

Which regulatory body oversees the safety and ethical considerations of genetically modified crops 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: C
Explanation:

The Department of Agriculture (USDA) is responsible for regulating the safety and ethical considerations of genetically modified crops in the United States.

Which genetic engineering technique involves introducing foreign genes into an organism's genome?

  1. Gene Editing

  2. Transgenesis

  3. Genome Sequencing

  4. Gene Therapy


Correct Option: B
Explanation:

Transgenesis involves the introduction of foreign genes into an organism's genome, allowing the organism to express the introduced genes and their associated traits.

In medicine, gene therapy aims to treat genetic diseases by:

  1. Replacing faulty genes with functional ones

  2. Introducing genes that produce therapeutic proteins

  3. Correcting genetic mutations

Gene therapy encompasses various approaches to treat genetic diseases by replacing faulty genes, introducing genes that produce therapeutic proteins, and correcting genetic mutations.

Which technology enables the sequencing of an organism's entire genome?

  1. CRISPR-Cas9

  2. Gene Editing

  3. Genome Sequencing

  4. Transgenesis


Correct Option: C
Explanation:

Genome sequencing involves determining the sequence of nucleotides in an organism's DNA, providing valuable insights into genetic variations and disease mechanisms.

Which ethical concern arises from the use of genetic engineering in agriculture?

  1. Potential for unintended environmental consequences

  2. Unequal access to genetically modified crops
