Correct Answer
(C) Bacterium
Solution & Explanation
Answer: (c) Bacterium Solution: In 1983 Eli Lilly, an American company, introduced the DNA sequences coding for the A and B chains of human insulin into plasmids of E. coli (a bacterium) to produce the insulin chains. So the genetically engineered organism used was a bacterium. NCERT Reference: Ch 10, p.182, line 10 — "In 1983, Eli Lilly an American company"; p.182, line 12 — "chains of human insulin and introduced them in plasmids"; p.182, line 13 — "of E. coli to produce insulin chains."
