Question 11

Analyze the ethical concerns raised by the potential long-term environmental consequences of genetically modified organisms (GMOs).

Accepted Answer

GMOs introduce new genes into native species, potentially disrupting ecosystems and raising ethical concerns.

Answer

GMOs have no ethical implications because they are only used in agriculture.

Answer

The long-term ecological effects of GMOs are fully understood, eliminating ethical concerns.

Answer

The ethical concerns about GMOs are less significant than their potential benefits, such as increased food production.

Question 12

Accepted Answer

Societal perspectives on GMOs are diverse, encompassing ethical, environmental, economic, and cultural considerations, influencing public opinion and policy-making.

Answer

GMO perspectives are solely based on scientific data, leading to a uniform public opinion.

Answer

Public opinion on GMOs is not influenced by societal perspectives.

Answer

Policy-making on GMOs is solely driven by scientific evidence, without considering societal perspectives.

Question 13

How has CRISPR-Cas9 gene editing technology transformed gene therapies for genetic diseases like sickle cell anemia?

Accepted Answer

CRISPR-Cas9 allows precise gene editing, enabling targeted correction of genetic defects causing sickle cell anemia.

Answer

GMOs are not directly involved in gene therapy, as gene editing techniques operate independently on human DNA.

Answer

CRISPR-Cas9 primarily targets bacterial DNA and has limited applications in gene therapy for human diseases.

Question 14

Which technique is employed to introduce foreign DNA into an organism?

Accepted Answer

Transformation, directly introducing DNA

Answer

Transduction, using viruses as vectors

Answer

Conjugation, exchanging genetic material through physical contact
