Practice questions testing deep understanding of GM crops, insulin production, and RNA interference.
Q1. Before the advent of genetic engineering, insulin for diabetic patients was extracted from the pancreases of slaughtered pigs and cattle. What was the major biological problem with this animal insulin, and how did Eli Lilly's "Humulin" solve it?
Q2. Assertion (A): RNA interference (RNAi) is used to create pest-resistant transgenic plants, like tobacco resistant to the nematode Meloidegyne incognita. Reason (R): RNAi works by producing a specific double-stranded RNA in the plant. When the nematode eats the plant, this dsRNA enters the nematode and physically destroys the nematode's messenger RNA (mRNA), silencing a critical gene and causing the nematode to die.
