STANDARD Zoology Transgenic Animals MCQ Question

Transgenic animals are engineered to express specific genes that enhance their sensitivity to toxic substances, allowing researchers to assess the potential harmful effects of drugs more effectively. This increased sensitivity (option C) enables the detection of lower doses of toxins that might not affect non-transgenic animals. In contrast, option A suggests intolerance to the drug, which does not facilitate toxicity testing, while option B implies increased resistance, which would hinder the assessment of drug toxicity rather than aid it. Thus, the goal of creating transgenic animals in this context is to ensure they are more responsive to toxic effects, making option C the most appropriate choice.
