Recombinant DNA for Insulin Production

Steps:

• Insert human insulin gene (DNA) into bacterial plasmid.
• Bacteria take up the recombinant DNA and express the human gene.
• This leads to assembly of amino acids into human insulin protein.
• Bacteria multiply, amplifying insulin production.

Why C is correct:

• In recombinant DNA technology, human DNA encoding insulin is inserted, directing bacterial ribosomes to assemble amino acids into the protein via translation, while bacteria replicate for mass production.

Why the others are wrong:

• A: Uses bacterial DNA, but insulin requires human DNA; multiplication is correct but incomplete.
• B: Uses bacterial DNA, which wouldn't produce human insulin; cell death doesn't occur.
• D: Multiplication is correct, but bacterial DNA insertion fails to make human insulin.

Final answer: C
