Question 2 • 2025-2026_MDCPS_2000315_Biology_1_A-CR

Which is a potential negative consequence of using genetically engineered medicine?

Answer

Gene markers that are resistant to antibiotics are used, providing the possibility for humans to have increased antibiotic resistance.

Products that are used to genetically engineer medicine are poisonous.

Restriction enzymes are used to create the medicine and have been known to cause cancer.

Medicine that is created this way is less effective than medicine that is created the traditional way.

Explanation

Antibiotic-resistance genes may be used as markers during genetic engineering. If those genes were transferred to harmful bacteria, they could contribute to increased antibiotic resistance, which is a potential concern. Restriction enzymes are tools used to cut DNA; they are not known for causing cancer, and genetically engineered medicines are not inherently less effective.
