Question 24 • CMS 2026-2027 Biology CREDIT RECOVERY

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

Answer

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

Products that are used to genetically engineer medicine are poisonous.

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

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

Explanation

A potential concern is that genetic engineering may use antibiotic-resistance marker genes. If those genes were transferred to bacteria associated with humans, the bacteria could become harder to treat with antibiotics. The other choices make unsupported claims: genetic engineering products are not inherently poisonous, less effective, or cancer-causing because restriction enzymes are used.
